ORNAMENTAL GRASSES & THEIR COMPANIONS - 2
Ornamental Grasses provide many benefits to a gardener. They can stand alone as a landcaping element or be incorporated into our garden beds to make a dramatic statement among other perennials. They can be mass planted for a different effect, with several plants of the same species together, or combined with other ornamental grass species or cultivars in myriad combinations. And for low-maintenance gardening they are unequalled. What else requires only an early spring cut-back to launch it into a summer-long performance?Note that heights given for ornamental grasses are for foliage only. Plumes can add several more feet to the overall height during bloom. Blooms of Ornamental Grasses are usually referred to as "inflorescences".
Rick Darke's Timber Press Pocket Guide to Ornamental Grasses belongs on your shelf of gardening literature. There's plenty of identification information about species and cultivars that you're sure to finding interesting and informative. Watch for many references to this volume below.
If you want on-line information about Ornamental Grasses and Sedges, their many different genera, species and cultivars, just follow the link to the BLUESTEM NURSERY home page. Be sure to check out their Grass-scapes link for images of the plumes of many and their Landscape Uses link so that you can find the correct spot to plant them for best growth potential.

Maiden Grass, Silver Grass and Eulalia are various names for these showy clumping warm season grasses, most ranging from 3 feet to 15 feet in height. There is even one listed below which tops out at a mere 18". Rick Darke's Timber Press Pocket Guide to Ornamental Grasses states that "All species and most cultivars prefer full sun sites.". Older clumps may require division when they begin to die out in the center. For best results perform this chore in spring or early summer.

Moor Grass, mostly warm-season clumping grasses, ranging in height from dwarf to giant, has some of the showiest plumage of all ornamental grasses. To avoid confusion, you should know that there are two distinct sub-species in this genus, differing considerably, particularly in height but in other characteristics as well. Knowing the difference will help with choosing their placement in the garden as well as the companions to plant with them.
Molinia caerulea 'Variegata': Variegated Moor Grass, 24-30", one of the best variegated ornamental grasses

Switch Grass, a warm season clump-forming grass form, is returning to popularity in North America where it was once a major part of the tallgrass prairie. It has been called one of the loveliest grass families and many of the available cultivar choices may be just perfect for your garden setting.

Fountain Grass, mostly warm-season, clumping grasses, produces showy flowers in a range of colours. In addition to the perennial forms below, there are several annual forms worth seeking out, from the shorter Pennisetum orientale & Pennisetum villosum to the aptly named 'Burgundy Giant'.
Pennisetum alopecuroides: Fountain Grass, 3-4'x24-30"
with: yellow daisies i.e. black-eyed Susan, Rudbeckia
with: Sedum 'Autumn Joy'
combined with: Sedum 'Vera Jameson' & Rudbeckia 'Goldsturm'

Check out the additional cultivars within the species Pennisetum alopecuroides below. Many are described as only hardy to Zone 6, which makes them unsuitable for my Zone 5 gardens. Will some prove hardier than expected? I can only hope:
Pennisetum setaceum 'Rubrum': Purple-Leaved Fountain Grass, not perennial, 3-4'x24-30"
- 'Cassion's Choice' - 3', brilliant red and yellow foliage in autumn

Canary Grass is invasive. The only species grown for ornamental use, Phalaris arundinacea, commonly known as Reed Canary Grass has several well-known cultivars including some nice variegated forms. The one below was once one of the few variegated grasses available. These days, the most suitable use for such highly invasive grasses may be in a container where its growth can be restrained.
Phalaris arundinacea 'Picta': Gardener's Garters, Ribbon Grass, green leaves with creamy-white stripes
very difficult to eradicate once it grows beyond strictly enforced boundaries
Moor Grass, cool-season clumping grasses, includes many forms excellent for use as groundcover or in mass plantings. Flowers are nondescript, but the foliage is handsome.
Sesleria autumnalis: Autumn Moor Grass, 18"x24", yellowish-green foliage
uses: good for mass planting
offset behind: Liriope muscari 'Big Blue'
beside: Pennisetum alopecuroides, Ilex x meserveae 'Blue Stallion'

Spartina pectinata: Prairie Cord Grass, 5-7'
synonym: Spartina michauxiana
beside: Spodiopogon sibiricus
beside & behind: Perovskia atriplicifolia
Spartina pectinata 'Aureomarginata': Golden-Edged Prairie Cord Grass, 5-7'x3'

Frost Grass, also called Graybeard Grass, are warm-season grasses with a low growth habit appropriate to smaller gardens. Very effective, whether planted alone or in groups.
Spodiopogon sibiricus: Silver Spike Grass, Frost Grass, Graybeard Grass, 42-54"x39"
sometimes incorrectly called: Muhlenbergia alpestris or Lasiogrostis splendens
