Canna or canna lily is the only genus of flowering plants in the family Cannaceae, consisting of 10 species. All of the genus's species are native to the American tropics and were naturalized in Europe, India and Africa in the 1860s. Although they grow native to the tropics, most cultivars have been developed in temperate climates and are easy to grow in most countries of the world, as long as they receive at least 6–8 hours average sunlight during the summer, and are moved to a warm location for the winter. See the Canna cultivar gallery for photographs of Canna cultivars.
Groundcover or ground cover is any plant that grows low over an area of ground, which protects the topsoil from erosion and drought. In a terrestrial ecosystem, the ground cover forms the layer of vegetation below the shrub layer known as the herbaceous layer, and provides habitats and concealments for terrestrial fauna. The most widespread ground covers are grasses of various types.
Liriope is a genus of low, grass-like flowering plants from East and Southeast Asia.
Glechoma hederacea is an aromatic, perennial, evergreen creeper of the mint family Lamiaceae. It is commonly known as ground-ivy, gill-over-the-ground, creeping charlie, alehoof, tunhoof, catsfoot, field balm, and run-away-robin. It is also sometimes known as creeping jenny, but that name more commonly refers to Lysimachia nummularia. It is used as a salad green in many countries. European settlers carried it around the world, and it has become a well-established introduced and naturalized plant in a wide variety of localities. It is also considered an aggressive invasive weed of woodlands and lawns in some parts of North America. In the absence of any biological control, research conducted by the USDA herbicides are relied upon particularly for woodland ecosystems. The plant's extensive root system makes it difficult to eradicate by hand-pulling.
Ophiopogon japonicus (dwarf lilyturf, mondograss, fountainplant, monkeygrass; Japanese: リュウノヒゲ ryu-no-hige or ジャノヒゲ ja-no-hige is a species of Ophiopogon native to China, India, Japan, Nepal, and Vietnam.
Ornamental grasses are grasses grown as ornamental plants. Ornamental grasses are popular in many colder hardiness zones for their resilience to cold temperatures and aesthetic value throughout fall and winter seasons.
Ardisia crenata is a species of flowering plant in the primrose family, Primulaceae, that is native to East Asia. It is known by a variety of names such as Christmas berry, Australian holly, coral ardisia, coral bush, coralberry, coralberry tree, hen's-eyes, and spiceberry. A. crenata is a compact shrub that reaches 1 metre (3.3 ft), often with a single stem. Leaves are dark green, thick, glossy, and have tightly waved edges The flowers are small, white or reddish, fragrant, and form clusters. The fruit is a glossy, bright red drupe. The seeds are able to germinate under a dense canopy and are dispersed by birds and humans.
Physostegia virginiana, the obedient plant, obedience or false dragonhead, is a species of flowering plant in the mint family, Lamiaceae. It is native to North America, where it is distributed from eastern Canada to northern Mexico. Physostegia are known commonly as obedient plants because a flower pushed to one side will often stay in that position. The name “false dragonhead” refers to the dragonheads of the related Dracocephalum, a genus to which the plant once belonged.
Thymus citriodorus, the lemon thyme or citrus thyme, is a lemon-scented evergreen mat-forming perennial plant in the family Lamiaceae. There has been a great amount of confusion over the plant's correct name and origin. Recent DNA analysis suggests that it is not a hybrid or cross, but a distinct species as it was first described in 1811., yet an analysis in a different study clustered Thymus citriodorus together with Thymus vulgaris, which is considered as one of its parent species.
Festuca rubra is a species of grass known by the common name red fescue, creeping red fescue or the rush-leaf fescue. It is widespread across much of the Northern Hemisphere and can tolerate many habitats and climates. It is best adapted to well-drained soils in cool, temperate climates; it prefers shadier areas and is often planted for its shade tolerance. Wild animals browse it, but it has not been important for domestic forage due to low productivity and palatability. It is also an ornamental plant for gardens.
Hakonechloa is a genus of bunchgrass in the tribe Molinieae of the grass family, Poaceae, native to eastern Asia.
Brunnera is a genus of flowering plants in the family Boraginaceae. They are rhizomatous perennials, native to the woodlands of Eastern Europe and North West Asia. They have hairy leaves and sprays of blue flowers in spring. Numerous cultivars are available, which are valued as groundcover in dappled shade. Some possess variegated foliage. The best known species is Brunnera macrophylla, known as Siberian bugloss.
Liriope muscari is a species of flowering plant from East Asia. Common names in English include big blue lilyturf, lilyturf, border grass, and monkey grass. This small herbaceous perennial has grass-like evergreen foliage and lilac-purple flowers which produce single-seeded berries on a spike in the fall. It is invasive to North America and considered a threat to native wildlife.
Leymus triticoides, with the common names creeping wild rye and beardless wild rye, is a species of wild rye. It is native to western North America from British Columbia to California and Texas.
Ophiopogon planiscapus is a species of flowering plant in the family Asparagaceae. It is a small evergreen perennial growing to 20 cm (8 in) tall by 30 cm (12 in)wide. It grows from short rhizomes, and bears tufts of grasslike leaves, from which purple or white flowers emerge in racemes held on short stems above the leaves. It is native to Japan, where it grows on open and forested slopes.
Elymus lanceolatus is a species of grass known by the common names thickspike wheatgrass and streamside wheatgrass. It is native to North America, where it is widespread and abundant in much of Canada and the western and central United States. There are two subspecies, subsp. lanceolatus occurring throughout the species' range and subsp. psammophilus occurring in the Great Lakes region.
Maranta leuconeura, widely known as the prayer plant due to its daily sunlight-dependent movements, is a species of flowering plant in the family Marantaceae native to the Brazilian tropical forests. It is a variable, rhizomatous perennial, growing to 30 cm (12 in) tall and broad, with crowded clumps of evergreen, strikingly-marked oval leaves, each up to 12 cm (5 in) long. The plant spreads itself horizontally, carpeting an entire small area of forest floor, sending roots into the substrate at each leaf node.
Digitaria didactyla is a species of grass known by the common names blue couch, Queensland blue couch, blue serangoon grass, green serangoon grass, blue stargrass, and petit gazon. It is native to Mauritius, Réunion, parts of mainland Africa, and Madagascar. It has been introduced widely outside its native range, mainly for use as a pasture and turf grass. It has naturalized in some regions.
Helichrysum thianschanicum is a species of flowering plant in the family Asteraceae. It is commonly known as silver spike or icicle plant. It is part of a large genus of over 500 species.
