Echinacea paradoxa is the only Echinacea species to feature yellow flowers instead of the usual purple flowers. This North American herbaceous perennial produces large, daisy-like flowers, 4 in. across (10 cm), with narrow, drooping golden-yellow rays surrounding a conical, chocolate-brown central cone. The lovely combination of the prominent central cone and thin golden flower petals makes this Yellow Coneflower one of the most attractive prairie perennials. Aside from the subtle form and color of its elegant flowers, Echinacea paradoxa also features a dark green foliage of long, narrow leaves with linear veining. Vigorous, this Coneflower is noted for its long-lasting blooms and its tolerance to almost everything!

Penstemon barbatus 'Coccineus' (Beardtonge) is a clump-forming perennial with erect, loose spikes boasting brilliant scarlet, tubular flowers borne in profusion in the spring and again in the fall. They rise above the lush foliage of lance-shaped, medium-green leaves. 

Stipa tenuissima (Mexican Feather Grass) is an exceptionally lovely and graceful ornamental grass that exhibits silvery-green thread-like leaves in late spring, that sway gracefully in the slightest breeze, delicately softening any landscape. All summer, it bears abundant feathery panicles, which are held a little above the foliage and can be used in dried arrangements. Native to the Americas, this perennial grass provides a fairly long-lasting display with its airy silky green leaves turning golden brown towards fall.

This Echinacea species gets the attention of many gardeners. Why? The lovely combination of the prominent central cone and thin, pale pink to purple flower petals gracefully hanging like tassels, makes them one of the most attractive prairie perennials. Aside from the subtle form and color of its elegant flowers, Echinacea pallida, commonly known as Pale Purple Coneflower also features a dark green foliage of long, slender, toothless leaves. Blooming from late spring to midsummer, this attractive upright perennial is worthy of a place in pollinator gardens, perennial borders, prairies, or wildflower gardens.

Striking, Eryngium yuccifolium (Rattlesnake Master) is an evergreen perennial with luminous clusters of small, egg-shaped flowerheads, 1 in. across (2.5 cm), tightly packed with tiny greenish-white flowers, subtended by white pointed bracts. Appearing at the top of smooth, stiff, branched stems in mid-summer, they rise atop a basal rosette of sword-shaped, spiny-edged, yucca-like, blue-gray leaves. Once credited with the curative power of treating rattlesnake bites, Eryngium yuccifolium is commonly known as Rattlesnake Master. And don't worry, it doesn't attract rattlesnakes!

Hardy and reliable, Agastache 'Black Adder' (Giant Hyssop) is a charming herbaceous perennial boasting bottle-brush, terminal spikes, 6-8 in. long (15-20 cm), packed with fragrant, tubular, two-lipped red-violet flowers emerging from dark buds. Blooming from mid-summer to fall, they provide a remarkably long floral display and add color as well as a lovely spiky texture to the garden.
