Alpine plume grass is a spectacular long-lived grass from high mountain meadows in central and southern Europe. A mature plant makes a dramatic specimen, with several dozen flower heads waving above a graceful fountain of fresh green foliage. The flowers persist from summer until the following spring when the entire plant should be cut back to make room for the new season’s growth. Unlike many other ornamental grasses, the foliage doesn’t die out in the clump’s center over time.

Native!  Big Bluestem is taller and has a wider blade than Little Bluestem and is somewhat upright but also arching. It also has attractive reddish and purple fall colors. Big Bluestem is one of the dominant components of the Tallgrass Prairies across the Great Plains, where it can reach 8’ in height. Here it can range from 2 to 5’ tall, depending on water and nutrients available. In late summer, Big Bluestem’s purplish red flowers appear in groups of three or six, which look like a turkey foot – hence the nickname: “Turkey Foot Grass”. The root system can extend down more than 10 feet. Each year, a third of these roots die, feeding soil microorganisms and opening up channels for water. This plant is drought tolerant once it’s established. Attracts birds and butterfly larvae.

Native!  Little Bluestem is very erect to 24”-30” with fine foliage and blooms in late summer-early fall. Blooms turn white and catch the early morning and late afternoon sun beautifully when back-lit. The foliage turns copper and looks good for a long time. Very drought-tolerant. Selections ‘The Blues’ and ‘Prairie Blues’ have very blue foliage during the growing season. ‘Blaze’ is a colorful selection of the common native in this region.

Side-Oats Grama is a smaller meadow grass than Bouteloua gracilis (Blue Grama). It’s seed heads and foliage turn a beautiful dark purple-red in fall.

‘Blonde Ambition’ was discovered in 2007 by David Salman of Santa Fe Greenhouses, who noticed an outstanding specimen growing within a stand of robust Hachita blue grama. At 28-32” it was taller and wider than the standard, its leaves were a bright blue-green and it was topped with a multitude of its distinctive flag-like flowers, although these were chartreuse rather than the usual black or brown and they were held appealingly at a 90 degree angle to the leaves. It was apparent this was a plant that could stand on its own as an ornamental.

This exceptional plant was found to have chartreuse flowers that turned blonde as the season progressed and the rigid stems popped back up after snowstorms, rather than remaining prostrate, so its season of attractiveness lasted well into the winter. Grow ‘Blonde Ambition’ in clay, loam, or sandy soils, with full sun and moderate to very low H2O.

The most popular and over-used ornamental grass, for good reason. Medium sized (to 4’ tall), very erect form, easy to grow and highly adaptable to everything but shade, very durable flower/seed heads remain attractive all summer, fall and winter. No fall foliage color. Cut down in early February. Try to avoid plantings that look like rows of soldiers standing at attention!

Hardy to Zone 4.

To 3’ or 4’ tall, with a graceful fountain-like or mounded shape, and waits until the end of the summer to flower. Can take some shade. Very pretty, with pinkish plumes that dry tan. No fall color. Plant Select. Should be used more.

A small fountain-like clumping sedge, 6-10”h x 10-12” w, very fine-textured, bright light green and very attractive. Native to woods in Eastern N. America, it grows well in dry shade or part shade. It mixes well with perennials and serves as a neat groundcover or edger. Its tenacious roots will prevent erosion on shady slopes, and it can grow among tree roots. Very small, attractive  blooms occur in spring, supporting beneficial insects.

This petite sedge is rhizomatous and spreads. Its long glossy blades are slightly variegated yellow and green, and curve to the ground, giving it a mop-headed look. Makes an excellent groundcover or small ‘lawn’ (just to look at, not to step on) in shady gardens, especially Asian-styled gardens. Almost evergreen.

A US native, though not native here, this grass grows well in part shade. The wide, bright green blades emerge from the stems at many heights, giving it a slightly bamboo-like look. The pendulous seed clusters in late summer are composed of very attractive flat, plaited spikelets, starting out pale green, later turning tan. Foliage stays green until fall, when it turns yellow. It will self-sow but is not difficult to control.

Native!  This medium-sized grass, to 2-3’ x 2-3’, loves to grow in sandy soil as its name suggests, but adapts to many soils with low to moderate moisture. It is effective in masses and can be an excellent component of a meadow. Reddish tones begin to show in late summer, and the haze of tiny purple-pink seeds in late summer are beautiful. Sand Love Grass tends to rot in the center as it gets older, and self-sows readily.

Evergreen. This year we carry F. glauca ‘Boulder Blue’, a 10”-tall selection with very blue foliage, good form, hardiness, longevity and drought-tolerance. We also have F. ovina “Sea Urchin”, smaller, finer texture, good for rock gardens or Asian-style gardens, and Festuca thurberi, which is native from 5,000’ to 10,000’ elevation and is nearly evergreen, to 12” tall.

A much sought-after modest-sized evergreen grass with powder-blue blades, and that has some shade tolerance. It forms an open, symmetrical mound of foliage from 12” to 24” high, and a bit wider, looking like the ‘big brother’ of Blue Fescue. Bloom stalks add another 12 to 18”, and provide interest for several months.

Vanilla Sweet Grass is an aromatic, cool-season perennial growing 10-24” tall, blooming in June to July, and spreading about 2 feet per year by underground rhizomes. The natural range of Sweet Grass is Greenland to Alaska, south to New Jersey, the Midwest, and Arizona, in zones 3 to 7. Its natural habitat is wetlands, prairies, and savannas in wet to medium moisture soils.

A sacred grass in Native American ceremonies, Sweet Grass is braided and burned as a ‘smudge’ to purify body and soul and invite the presence of good spirits. The glossy green leaves have a pleasant vanilla fragrance. Because of its aggressive, rhizomatous nature it can be difficult to eliminate if it has spread to areas where it is not wanted.

Though Sweet Grass prefers rich, moist soils, it will grow in almost any soil that receives a minimum of a half day of sun. Sandy, well-drained sites will require mulch and watering during times of low rainfall. Add compost to sand or clay soils. The preferred pH range is 6 to 8.
