Plant of the Month (October) : Western Pearly Everlasting – Anaphalis mararitacea

Western Pearly Everlasting (Anaphalis mararitacea): looks good in October

The gardens of Western Colorado are looking very fall-like by October. There are still plenty of yellow flowers and changing leaves. But the overall trend is towards oranges-brown, so contrasting flowers and foliage play an important accent role. One of our favorite fall accents in Mother Nature’s Montrose Garden is the Western Pearly Everlasting, Anaphalis mararitacea. The scientific name is pronounced: a-NAF-uh-lus mar-gar-ee-tuh-KEE-uh.

The genus Anaphalis, in the Sunflower family (Asteraceae), primarily grows in Central Asia.[1] Its members are known for their hairy-white foliage. Most also have flower bracts that remain on the plant for months after flowering (hence the common name ‘Everlasting’). Both the foliage and flowers/bracts provide good contrast against the greens and browns of other plants.

contrasts with other native plants

The sole North American Anaphalis is our Plant of the Month, Anaphalis mararitacea, which is also native to Central Asia and India. [2] Western Pearly Everlasting (also known as Common Pearly Everlasting or simply Pearly Everlasting) has a wide North American range. It grows wild from Canada to northwestern Mexico, most commonly in mountain meadows, dry woods (often with aspen or mixed conifer-hardwood), along roads/trails and in other open (often disturbed) places.

Anaphalis mararitacea grows on Colorado’s Western Slope and in some southern Colorado counties. It is ‘common in mountain meadows and forest openings from the montane to subalpine, 7800-11,500 ft.’ [3] For good photographs in Western Colorado see reference 4 (references at end of post).

Western Pearly Everlasting (Anaphalis mararitacea): growth habit

Pearly Everlasting is an herbaceous perennial that dies back completely in cold weather. The plants are robust and upright (above), with heights of 1-3 ft. [0.3 to 1 m.] and widths of 1-2 ft. In Mother Nature’s Montrose Garden, plants are usually around 1 ft tall and a little wider. Branches are brittle and covered in white trichomes (hairs). Plants spread via underground stems (rhizomes) and clumps or patches are often seen in the wild and in gardens.

The leaves are medium to deep gray-green above, while the undersides are wooly and soft (photo above). Largest leaves are 3 to 5 inches long, narrow and alternate. The foliage has a faint balsamic scent. Plants are dioecious, with separate male and female plants (below).

Western Pearly Everlasting (Anaphalis mararitacea): flowering plant

As is typical of the Sunflower family, flowers are clustered in flowering ‘heads’. The tightly clustered buds resemble pearls, hence the common name ‘Pearly Everlasting’. What’s unusual about the flowering heads is that they contain only the reproductive disc flowers - no showy, colorful ray flowers. The apparent ‘petals’ are actually thin bracts (modified leaves surrounding flowers).

Western Pearly Everlasting (Anaphalis mararitacea): male flowers

Western Pearly Everlasting (Anaphalis mararitacea): female flowers

Male plants contain only male (staminate) flowers; female plants only female (pistillate) flowers (above). The bracts of female flowers remain closed until flowering is complete; the bracts of male flowering heads are more spread open. And only the female plants produce seeds; production of fertile seeds requires both male and female plants and the services of pollinators. If you raise your plants from seed, you’ll likely get some of each sex.

Western Pearly Everlasting (Anaphalis mararitacea):
female flowers going to seed in fall

Pearly Everlasting blooms from mid-summer until early fall, with seeds developing in October in our garden. The seeds are small, light, with a tuft of white hairs. Seeds are spread by the wind, making this a good candidate for naturalizing.

Anaphalis mararitacea can be grown in USDA Zones 3 through 8 or 9. It is quite a tolerant species: it’s not particular about soil texture and accepts soil pH from 5 to 8. It likes sun but will tolerate some shade. And it’s quite drought tolerant once established (irrigate several times a month in dry summers). In fact, the one thing it doesn’t like is water-logged soils.

Like many Western native plants, Pearly Everlasting needs no fertilizer in the ground. If grown in containers, we’d give it a dose of half-strength fertilizer in spring.

Western Pearly Everlasting (Anaphalis mararitacea): seeds

This is an easy plant to grow and seeds are readily available from seed sources. Seeds can be planted outdoors in prepared seed beds. Alternatively, they can be sown outdoors after the last spring frost. Seeds purchased from growers have usually been pre-treated with a cold exposure. If you collect your own seeds, you will get better germination if seeds are exposed to cold. For good instructions on cold treatments see reference 4 (references).

Lady Butterfly on Lilac

One of the many reasons we like Pearly Everlasting is its habitat value. Several types of native bees, as well as butterflies and other pollinators visit the flowers. The foliage provides larval (caterpillar) food for American lady (Vanessa virginiensis) and painted lady (Vanessa cardui) butterflies. The caterpillars create protective ‘tents’ made of leaves and silk at the ends of the flowering stalks. They emerge to feed under the protection of darkness.

If you’re interested in traditional uses, Anaphalis mararitacea will appeal. Young leaves and plants can be cooked and eaten as greens. The scented flowers and foliage can be used as incense, used as tea (fresh or dried) or dried to scent linens and clothes. The plant dries/stores well, and tea from the dried plant makes a sweetly scented tea, alone or combined with other herbal tea ingredients. Yellow, green and brown dyes can also be produced from flowers and foliage.

Pearly Everlasting has a history of use as a medicinal plant, as an infusion (tea), tincture and poultice. An infusion (tea) is good for seasonal allergies. [5] It was also used traditionally to treat ‘diarrhoea, dysentery and pulmonary affections’.[6] Poultices made from Anaphalis mararitacea were applied to burns, sores, ulcers, bruises, swellings and rheumatic joints. And steam from an infusion has been inhaled to treat headaches and sinus congestion. [6]

Western Pearly Everlasting (Anaphalis mararitacea): in garden

There are also many horticultural reasons to include Pearly Everlasting in the home garden. First, it’s an easy plant to grow that succeeds in many gardens. It can be started inexpensively from seed and it naturalizes well in bare areas of the garden.

This is a must addition to a pollinator or butterfly garden. You might plant it in an herb garden or near a vegetable garden. The flower bracts make a lovely, long-lasting fall cut flower, and are often so used. Its foliage and flowers provide attractive contrast in the perennial bed or water-wise prairie/meadow, particularly in fall.

We like it along pathways, driveways, etc. And its scent is so pleasant that it deserves a place near seating areas, perhaps grown in containers on a patio. In short, we think there’s lots to recommend Western Pearly Everlasting. Do you have a place to tuck this little plant into your garden?

Plant of the Month (September) : Upright Prairie Coneflower / Mexican Hat – Ratibida columnifera

Upright Prairie Coneflower (Mexican Hat; Ratibida columnifera):
fall color for the garden

Wow, it’s already September! The days of summer go quickly in a garden. Some of the early bloomers have already gone to seed. But many late summer species are adding color (and food) to the September garden. One such plant is the Upright Prairie Coneflower, Ratibida columnifera. The scientific name is pronounced ruh-TIB-ih-duh kol-um-NEE-fer-uh.

The genus Ratibida, member of the Sunflower Family (Asteraceae), consists of seven species native to North America. Several are limited to Mexico, while others are more widespread in the U.S and Mexico. Two species, Ratibida tagetes and Ratibida columnifera, are native to the eastern plains and southwestern counties of Colorado.[1] Fortunately, these two species grow well in gardens on the Western Slope and in the Four Corners region, as well as other in other parts of the U.S.

Ratibida columnifera’s native range extends from SE British Columbia, Canada, south to Mexico and east to the American Great Plains. In the wild, Upright Prairie Coneflower can be found in several Colorado plant communities, including pinyon-juniper and ponderosa pine woodlands, prairies, grasslands, and disturbed areas, from about 3500 to 7000 ft. elevation. Sites are often sunny, dry and open; the species is common along roadsides in some areas. All this hints at a tough, resilient plant, which the Prairie Coneflower is, indeed!

foliage

Ratibida columnifera is a clump-forming, herbaceous perennial. Plants are usually 1-2 ft. tall, but may be up to 3 ft. The leaves, which can be up to 6 inches long, are deeply lobed (above), giving the plant a lacy appearance. The leaves and stems are medium green and the stems are roughly hairy. Plants have a stout, deep taproot.

Upright Prairie Coneflower (Mexican Hat; Ratibida columnifera):
flowering plant

Upright Prairie Coneflower is a late-summer bloomer in our area, most often from August through September, but sometimes as early as July – even June at lower elevations. As is typical of the Sunflower family, flowers are clustered in flowering heads. Individual flowering heads occur at the tips of slender stems, which may be erect or drooping. The flower heads look somewhat like a Mexican sombrero, hence the common name ‘Mexican Hat’.

The larger ray flowers (above) may be entirely yellow, yellow with maroon blotches or even completely dark red-brown and are characteristically reflexed (bent away from the disc flowers and towards the stalk). We grew our plants from seed and most have the yellow-and-maroon ray flowers, although the yellow form is more common in the wild. The ray flowers, while showy, are infertile.

ripening seeds

The central disc flowers, which are dark purple, are clustered about a central cone that rises an inch or so above the ray flowers. These tiny flowers are fertile and attract native bee pollinators. Mature seed heads (above) have a pleasant aroma. The seeds are dry achenes. Ratibida reseeds well, making it a good plant for naturalizing. Seeds can be easily collected for spreading to other parts of the garden – or giving away to friends and neighbors.

Ratibida columnifera is easy to grow from seed. The best way is to simply scatter seeds in the fall, lightly raking them in so they are barely covered. Seeds benefit from the winter chill and will sprout in spring. Alternatively, seeds may be planted in spring, after storing them (dry, in a plastic bag) in the refrigerator for 3 months.

Upright Prairie Coneflower (Mexican Hat;
Ratibida columnifera): seedlings

Grow Prairie Coneflower in full sun or part-shade, in USDA Zones 3-10. It tolerates most types of soils and most pH levels encountered in gardens. It needs no additional fertilizer unless grown in containers. And it tolerates medium-dry soil conditions – a boon to Western gardeners. In fact, this species is fairly drought tolerant, though irrigation can extend the bloom season. It is mostly disease and pest-free. And it can hold its own against other plants. Its only drawback is that it may be too successful in competing with weaker species.

Why consider Upright Prairie Coneflower for your garden? Well, it’s easy-to-grow and you ultimately get a lot of plants from a packet of seeds (what a bargain!). It’s a great plant for filling bare spots; you can always remove plants when you want to replace them with something else. You can grow it in a deep pot on a patio if that’s all the garden you have. But there are many additional benefits to planting Ratibida columnifera.

Upright Prairie Coneflower (Mexican Hat; Ratibida columnifera):
good filler plant in new gardens

It's a great habitat plant, attracting both specific and generalist native bee pollinators. Caterpillars of some moths feed on the foliage. And seed-eating birds love the seeds in summer/fall. In fact, some people grow this plant just for the birds!

Upright Prairie Coneflower (Mexican Hat; Ratibida columnifera):
Bumblebee appraches

Both flowers and foliage have a tradition of medicinal use. Infusions of the foliage have been used as a topical (applied to skin) agent to treat painful rashes and poison ivy; infusions of the flowers for headache. [2] The flowers can be used to make a yellow-orange natural dye.

Upright Prairie Coneflower (Mexican Hat; Ratibida columnifera):
looks especially good with native grasses and wildflowers

We like the look of Upright Prairie Coneflower in the garden. It pairs well with its natural companions: western wheatgrass, bluebunch wheatgrass, prairie Junegrass, Sandberg bluegrass, common gaillardia, white and purple prairie clover, big sagebrush, and western yarrow.[3] It provides a touch of fall color against the yellows and purples of other sunflowers and agastache. It’s a nice size, fitting well between the lower groundcovers and spikes of taller plants. And it’s an easy naturalizer, which is great for larger gardens.

So, there are many reasons to consider Ratibida columnifera for the home garden. Perhaps you should order some seeds for fall planting?

Upright Prairie Coneflower (Mexican Hat; Ratibida columnifera):
good choice for gardners in USDA Zones 3-10.

Plant of the Month (August) : Fourwing Saltbush – Atriplex canescens

Fourwing Saltbush (Atriplex canescens): Mother Nature's Montrose Garden

As the climate becomes more variable, Western gardeners are switching to plants known for their flexibility and resilience. One such shrub – which also serves as a nice background to flowering plants – is the native Fourwing saltbush, Atriplex canescens. The scientific name is pronounced: AT-try-plex kan-ESS-sens.

The genus Atriplex, the Saltbushes or Oraches, contains over 200 species worldwide and is currently assigned to the subfamily Chenopodioideae of the family Amaranthaceae (note: formerly known as the family Chenopodiaceae). [1] Saltbushes grow in a wide range of habitats, from dry deserts to sea coasts and other moist places. They are known as saltbushes because they can grow in salty soils, often ‘harvesting’ and sequestering salt from the environment. They have also developed several adaptations to dry conditions (more on this below).

Fourwing Saltbush (Atriplex canescens): San Miguel Co, CO.

Fourwing saltbush is a common shrub or sub-shrub (part-woody plant) of western North America. Its range stretches from Western Canada east to North Dakota and south to northern Mexico and Baja California. It is a common sight in many Colorado counties, usually growing on ‘dry slopes and plains, 3800-8800 ft’. [2] It typically – but not always - grows in dry, alkali and often salty soils. In Western Colorado, such soils are often associated with ancient shallow seas.

Fourwing Saltbush (Atriplex canescens): growth habit

Atriplex canescens is a mounded medium to large shrub, typically 3-4 ft tall in sites with little rainfall, but reaching heights of 6-8 ft or more in very favorable sites. The width ranges from two to eight ft. The form is variable across the species’ range; in some places almost tree-like, while in other sites low and compact. Common garden studies (species from different sites raised in the same ‘garden’) suggest that the differences are likely genetic in origin. [3]

Fourwing Saltbush (Atriplex canescens): foliage

Fourwing shrubs are many-branched and evergreen to semi-evergreen, losing at least some leaves to winter cold and/or drought. There is considerable variability in foliage characteristics. But in all sites, plants appear silvery green in contrast to other shrubs. This is due to several factors including: 1) scales that cover young leaves; 2) trichomes (plant hairs) that cover older leaves and small branches; 3) on salty sites, a crust of salt crystals exuded by the trichomes.

The growth rate of Atriplex canescens is at least partly dependent on soil moisture. This plant is an opportunist, growing quickly when resources are abundant and more slowly in times of drought. Its root system makes the most of any soil moisture it receives. Like many of our most drought-tolerant Western shrubs, Fourwing saltbush has both a network of shallow roots and a deep taproot (20 ft. to as much as 40 ft. deep). The roots can utilize both monsoonal moisture and deeper soil water reserves. Not surprisingly, plants in the wild are long-lived, even in harsh climates.

Fourwing Saltbush (Atriplex canescens): in wild

Fourwing saltbush is dioecious; male and female flowers occur on separate plants. But that’s just part of the story. Plants can change sex, usually from female to male, in times of stress (like drought). [4] This is yet another adaptation to harsh and variable conditions.

Fourwing Saltbush (Atriplex canescens): male flowers

Fourwing saltbush isn’t a species to plant for flowers. Both male and female flowers are small and yellow-brown. But the seeds (female plants only) are housed in an interesting dry fruit with four ‘wings’ (bracts) which is unique to the species and attractive in fall and winter (below).

Fourwing Saltbush (Atriplex canescens): green fruits

Fourwing Saltbush (Atriplex canescens): ripe fruits

Atriplex canescens is an important habitat plant in the wild. The fruits and seeds are consumed by birds (including quail, grouse and other birds), rabbits and other small mammals. The fruits and foliage are browsed by Jack rabbits, bighorn sheep, antelope, deer and elk in fall and winter. This browse is high in protein and considered a nutritious food source. Shrubs are often browsed severely by spring (see photo, below). Shrubs also provide cover for small and medium-sized animals and birds. And insects, including lacewings, ladybugs, hoverflies and the larvae of Mojave & Saltbush Sootywing Skippers, eat either the foliage or insects on it. [4,5]

Fourwing Saltbush (Atriplex canescens): browsing elk

Fourwind saltbush is easy to grow in USDA Zones 6-10. It tolerates a wide range of soil textures, from sandy or gravelly to loams, with pH from 6.5 to 9.0 (alkali). It can be grown in full sun, even in hot gardens, but also tolerates some shade. It does need good soil drainage, particularly in areas with abundant rain, and is very drought tolerant once established.

Give it weekly water for the first summer or two, then once a month or less thereafter. In fact, there’s a greater danger over over- than under-watering established plants. Plants may be susceptible to root fungi, so plant them in a drier part of the garden, if necessary.

Fourwing Saltbush (Atriplex canescens): tolerates
drought and salty soils

As mentioned above, wild Fourwing shrubs are often well-browsed during fall and winter. They are designed to take a yearly shearing, so don’t hesitate to cut branches back by 1/3 in late winter or early spring. Pruned plants will be heathier, bushier and better looking than those left unpruned. And that’s about it for this hardy, disease-free shrub.

Fourwing Saltbush (Atriplex canescens): fruits are showy

So how can Atriplex canescens be used in the garden? If you have a hot, dry area where little else grows, you might want to consider it. It’s a good alternative to the cacti (or non-living ground covers) often used in such situations. If given a yearly pruning it’s tidy enough for the front yard; no one will even suspect it’s a native! It is also a good choice for a sheared hedge, due to its dense foliage; or can be included in a mixed hedgerow.

Fourwing Saltbush (Atriplex canescens): good choice
for dry conditions

In areas where Fourwing saltbush is native, it can provide an effective transition to wildland areas or a backbone shrub for local native plantings. We like it mixed with other native shrubs and flowering perennials (below). The silvery-green color of Atriplex canescens contrasts beautifully with the silvers and deep greens of other plants. It is relatively fire-resistant compared to other Western native shrubs, which is another plus. And, of course, its habitat value makes it a good choice for attracting wildlife.

Fourwing Saltbush (Atriplex canescens): foliage provides
nice contrast year-round

Atriplex canescens has been put to good use by humans as well. The leaves can be harvested and eaten, raw or cooked, most times of the year. The one exception is if your soil is high in selenium; this plant is a selenium-accumulator, so leaves should not be eaten from selenium-rich soils. The seeds are tiny, but can be ground for flour or pinole. [4]

The leaves produce a soapy lather for hair washing or to relieve itchy skin, rashes and insect bites. Leaves and roots can be used to make a soothing poultice for insect bites and stings. [6] The Hopi burn green foliage for an ash that enhances the color of blue corn products. This ash can also be used as a baking powder substitute. [3] And the foliage yields a yellow dye.

We are big fans of Fourwing saltbush. It’s a tough-as-nails, drought tolerant shrub that adds beauty and usefulness to the garden. It isn’t showy, but it fills a niche that few other native shrubs do so well. It is most often available from local native plant nurseries, though we suspect it may become more common in the future. We suggest you seriously consider it for your future-resilient garden!

Plant of the Month (July) : Plains (Dyer’s) Coreopsis – Coreopsis tinctoria

Plains (Dyers) Coreopsis (Coreopsis tinctoria): Great native wildflower for home gardens

Seems like one long heatwave this summer in the Western U.S. Here on the Western Slope of Colorado, I think we’re going for the gold! Cheerful garden flowers can soothe when the heat threatens to get you down. And when the plants are also easy-to-grow? That sounds like Plains Coreopsis (Coreopsis tinctoria). The scientific name is pronounced cor-ee-OP-sis tinc-TOR-ee-uh.

Plains coreopsis has been given several scientific names over the years: Calliopsis bicolor; Coreopsis atkinsoniana; Coreopsis cardaminefolia; Coreopsis similis; Coreopsis stenophylla; and several named varieties of Coreopsis tinctoria. You can still see this species being sold as Calliopsis in the nursery trade.

Among the many common names given this species are Dyer’s coreopsis, Golden tickseed, Garden calliopsis, Elegant coreopsis, Good neighbors calliopsis, Cress-leaved coreopsis and Nuttall’s weed. The name Coreopsis comes from the Greek words koris (bug) and opsis (like); the shape of the seed resembles a bug or tick. [1] The specific name, tinctoria, refers to the plants properties as a dye plant (more below).

Plains coreopsis is native to much of the western and southern U.S. and is particularly common in the Great Plains states. In Colorado, Coreopsis tinctoria is native to the northeastern counties. But the species is widely planted throughout the U.S. and Europe, and has naturalized in areas outside its native range. In the wild, Plains coreopsis is found in moist – often disturbed – places such as prairies, plains, meadows, pastures and roadsides.

Plains (Dyers) Coreopsis (Coreopsis tinctoria): growth habit

Plains (Dyers) Coreopsis (Coreopsis tinctoria): foliage

Coreopsis tinctoria is an herbaceous annual (sometimes a short-lived perennial). It grows 1-4 ft (0.3-1.3 m.) tall and 1-2 ft wide. In our experience, the plant grows taller and fuller with more water. The plants are upright with stiff stems and lacy foliage. The leaves are simple- or double-pinnate and medium green in color (above).

Plains (Dyers) Coreopsis (Coreopsis tinctoria): flowering plant

Plants flower from summer to fall, depending on local conditions. Plants can flower for a month or more, particularly if faded blooms are dead-headed. The flowers are compound (typical for Sunflower family), with dark maroon disc flowers (center) and ray flowers that may be yellow with a maroon dot/splotch or almost entirely maroon (above). A single plant can have a range of flower color variants.

Plains (Dyers) Coreopsis (Coreopsis tinctoria): close-up of flower head

The flowers face the sun, moving on their slender stalks throughout the day. Grow Coreopsis where you can enjoy their spectacular colors, with the sun at your back. And don’t hesitate to harvest some flowers to enjoy indoors. They make good cut-flowers and add a nice touch of color to a mixed bouquet.

Coreopsis tinctoria re-seeds nicely in many gardens, so this is an easy plant to naturalize. Just leave at least some flowers to produce seeds. When the flowering heads are dry (about 4 weeks after flowers fade), scatter the seeds where desired. Alternatively, you can clean the seeds and save them for planting in the spring. Rub the dried flower heads between gloved hands, releasing the small seeds. Gently blow away the chaff, then store fully dry seeds in a sealed container in a cool place.

Plains (Dyers) Coreopsis (Coreopsis tinctoria): emergent seedlings

Plains (Dyers) Coreopsis (Coreopsis tinctoria): seeedlings ready to plant out

Seeds can be planted in prepared beds in spring or grown in pots indoors and then planted out. Seeds need no pre-treatment and are easy to grow. Barely cover the seeds - they need light to stimulate germination. The photos above show seedlings at two different stages. Note that the emerging leaves are simple compared to mature leaves.

Plains coreopsis is not a fussy wildflower. It will grow in most soils and does well in full or part-sun. It is said to favor a wide range of soil pH – from 5 to near 8 (Mother Nature’s Montrose Garden). Young plants need good soil moisture, but taper off the water as plants become established (and particularly after they start to go to seed in later summer or fall). In our garden it has not experienced any serious pests or diseases, although slugs or snails might be bothersome in a moister climate. Taller plants may need support if you live in a windy area.

Plains (Dyers) Coreopsis (Coreopsis tinctoria): pollinator

Plains (Dyers) Coreopsis (Coreopsis tinctoria): bee pollinator

So, why grow Coreopsis tinctoria? Well, it’s an easy-to-grow annual wildflower that can be grown in small places, including in containers. Its flowers add a cheery note to any garden – large or small. If you desire to create habitat, this is a great plant for native pollinators and birds. The flowers ‘provide nectar and pollen to a wide variety of insects, including long-tongued bees, short-tongued bees, wasps, flies, butterflies, skippers, and beetles.' [2] We’ve noticed that some bee species seem particularly drawn to the darker flowers, while others visit the bi-color flowers (above). And seed-eating birds will thank you for the seeds.

Plains (Dyers) Coreopsis (Coreopsis tinctoria): dye bath

Plains (Dyers) Coreopsis (Coreopsis tinctoria):dyed yarn

The flowers contain several chemicals used as natural dyes. Colors ranging from yellow to mahogany can be produced by altering the pH of the dyebath. The dyes are readily released from fresh or dried flower heads. Just pour hot water over the flowers and wait an hour or so. The red colored water can be used to dye wool or silk. The red dye chemicals will attach first, then the yellows, so different colors can be obtained from a single dye bath. We’ll talk more about natural dye methods in a future posting.

Coreopsis tinctoria has a medicinal tradition as well. An infusion (tea) from the plant has been used as a tonic, and for internal pains and bleeding. Zuni women desiring a female child would also drink such an infusion. [3, 4]

Plains (Dyers) Coreopsis (Coreopsis tinctoria): in
Mother Nature's Montrose Garden

Plains coreopsis provides cheerful summer color in the garden. It looks spectacular when massed or contrasted against green background foliage. It’s a good filler around growing shrubs and perennials. Some gardeners include it in a cuttings garden or herb garden. It will attract a range of pollinators if planted among your vegetables. It is also effective when combined with native grasses and other native wildflowers for a meadow or prairie planting.

Seeds are readily available from many on-line seed sources. If you desire specific characteristics, you can choose from several available cultivars. But the straight species is a delight, so there’s something for everyone. Plan to order some seeds this summer for fall planting. You’ll be the envy of your friends and neighbors next summer (and you’ll be able to share some seeds)!
