Keeled Garlic / Witch’s Garlic (Allium carinatum ssp. pulchellum)

16-20” tall, Perennial Bulb, Zone 5. Supports bees & butterflies

Purple stems support 2-3″ graceful clusters of violet-pink pendant bell-shaped flowers that look like exploding fireworks! Produces perennial clumps with slender grassy foliage and blooms for several weeks in mid-summer. The nectar-rich flowers are adored by bees and butterflies. Naturalizes in meadows, borders or rock gardens. Thrives in most soils with moderate to low moisture; can go dry after bloom. 1810 heirloom, native to Southern & Central Europe.

Rose Milkweed, Swamp Milkweed, (Asclepias incarnata)
15-36” tall x 15-18” wide, Full Sun, Zone 3/4, Deer-resistant, Attracts butterflies, native & honeybees, hummingbirds
A native, tap-rooted perennial forming stately clumps of upright stems with long narrow leaves and 2-3” flat heads of pretty soft mauve pink flowers, composed of many small intricate flowers with a lovely vanilla fragrance. Often found in wetland settings, but grows in the garden in moist, seasonally moist, or average soils, and blooms in July and August. Later, attractive slender upright pods form, great in dried arrangements. Rose Milkweed is larval host to Monarch and Queen butterflies.

Orange Butterfly Milkweed, Pleurisy Root (Asclepias tuberosa)
15-24” tall x 15-18” wide, Full Sun, Zone 4, Attracts butterflies, native & honeybees, hummingbirds.
The glowing orange flowers of this drought-tolerant, perennial native wildflower are irresistible to pollinators and people. A bushy perennial, it is prized for its large, flat-topped clusters of bright orange flowers atop strong flowering stems. Mature plants can make as many as 20 stems. Abundant stiff, lance-shaped leaves provide a dark-green backdrop for the showy flower heads, and the plant has no milky sap.
Milkweeds (Asclepias) provide essential habitat for the beloved Monarch butterfly, being the only plants on which Monarch caterpillars will feed. It is also a larval host for Gray Hairstreak and Queen butterflies, and a nectar source for bees, hummingbirds and adult butterflies. Orange Butterfly Milkweed is one of the best varieties for ornamental gardens, as it is tap-rooted and does not spread by underground roots. This long-lived, tap-rooted plant needs a couple of growing seasons to establish its deep roots and reach mature size. It prefers dry, well-drained loam soils, especially sandy soils. Asclepias tuberosa is also known as Pleurisy root, and was used by First Nations peoples to treat a variety of respiratory problems, and is still favored by herbalists. Native in most of the continental US from Maine to California.

Purple Prairie Wine Cups, Poppy Mallow (Callirhoe involucrata)
5” tall x 24-36” wide, Full sun, Zone 4, attracts bees
This sprawling perennial is a Colorado prairie native and grows wild from Texas to Canada. The large wine-magenta flowers bloom throughout spring and summer, with peak bloom in mid spring. Excellent as a cascading rock garden plant or groundcover, spreading to three feet, and its long tap root makes it very drought and heat tolerant. A 1999 Plant Select introduction.

‘Beatlemania’ Mop-headed Sedge (Carex caryophyllea ‘Beatlemania’)
6” tall x 12-24” wide, Part to full shade, Hardy to -20 °F, Zone 5 ‘Beatlemania’ is a lovely, fine-textured, slow-spreading dark green sedge with gold leaf edges. It lends an ‘Asian’ look to the ground-plane of the shaded woodland or contemplative garden, mixes well with Hosta and other shade perennials, and is especially effective as an understory for dwarf conifers or Japanese maples, draping over stone walls, and in rock gardens. The arching narrow variegated leaves create a 6” tall, dense mop-headed mound that spreads slowly by shallow rhizomes, but is not invasive, and is easily controlled by trimming. Cut the foliage to the ground in March before new growth begins. ‘Beatlemania’ appreciates moderate moisture and compost-amended soil. In our home garden, we grow it in a partly shaded garden under a deciduous tree, where it is watered deeply about every 10 days.

Cutleaf daisy, Engelmann’s daisy (Engelmannia peristenia)

18-24” tall x 18” wide, Full to Part Sun, Deer-resistant,
Another tough Colorado native needing little to no care, with its clumps of attractive cutleaf foliage throwing 2′ long flowering stalksof bright lemon-yellow flowers that continue blooming throughout the season from May to frost.  Attracts native & honeybees, butterflies. A 2015 Plant Select Introduction

‘Undaunted’ Ruby Muhly grass (Muhlenbergia reverchonii)

24-36” tall x 18-24” wide, Full Sun, Zone 5

A beautiful medium-sized, cold-hardy, native clumping grass, Undaunted® Ruby Muhly   makes a very showy late summer/fall display when its fine-textured, soft green mound of foliage is covered with a glowing mist of  bright red-pink flower spikes. The grass and seed heads turn an attractive tawny brown in winter. We recommend planting it in drifts of 3 or more plants for more impact in the garden. Wonderful planted with asters and other fall-blooming perennials. This long-lived and well-behaved ornamental grass is also deer-resistant and easy to grow, tolerating most soil types (including heavy alkaline clay), heat, cold, and drought. Native to N. Texas,S. Oklahoma. Designated Plant Select 2014

Scarlet Bugler (Penstemon barbatus)

18-36” tall x 1-2 ’wide, Full Sun, Zone 4, Deer-resistant, Attracts Hummingbirds, Butterflies
Scarlet Bugler is a tried and true, trouble-free native to rocky slopes and open woodlands in Southern Colorado and other parts of the Southwest. 2”-long brilliant scarlet tubular flowers are borne in profusion on tall slender stalks in June, and re-bloom can occur if dead-headed. It is a striking addition to the naturalistic water-wise garden. Scarlet Bugler continues when Penstemon eatonii, the earlier tall scarlet beard-tongue, has finished blooming. Both are magnets for hummingbirds. This erect, clump-forming perennial rises from an evergreen basal rosette of glossy, lance-shaped leaves. Scarlet Bugler is easy to grow in most dry to medium, well-drained soils, including shallow, rocky soil, in full sun or light shade. Avoid wet or poorly drained sites.

Rock Soapwort (Saponaria ocymoides)

4-5″ tall x 15-24” wide, Full Sun or Morning Sun, Zone 2/3, Deer-resistant, Attracts Butterflies & Bees

Rock Soapwort is a vigorous, log-blooming, low creeping Old World wildflower that will carpet the late spring/early summer garden with bright pink flowers. It is splendid spilling down sunny slopes or over rock walls.  Rock Soapwort makes a great semi-evergreen ground-cover for our short season climate and is especially valuable in gardens above 7,000’. It thrives in most soils, including clay, and is drought-tolerant once established. Prune plants back by half immediately after blooming to maintain compact habit and prevent reseeding. Do not prune for winter.

Giant Sacaton grass (Sporobolus wrightii) 5-6’ tall x 3-5’ wide, Full Sun or Partial Shade, Low to moderate water, Zone 5

A striking xeric, southwestern native grass. The golden seed heads can easily reach six feet tall, making it a great replacement for non-native, water-loving grasses like Plume Grass and Pampas Grass. The plant can ultimately reach five feet wide, adding impressive structure to the naturalistic landscape. It gives scale, drama and movement to summer and fall-blooming water-wise plantings. The seeds provide forage for songbirds. Giant Sacaton is fast and easy to grow in most soils and is very drought tolerant, but appreciates a couple of deep waterings in the driest months. Cut to the ground in early spring to remove the previous year’s dead leaves before new growth begins. Use as a specimen or in rows as a windbreak or living fence. Designated Plant Select 2006

Sedum sediforme ‘Turquoise Tails’:
