Cerastium tomentosum | |
Cerastium tomentosum (snow-in-summer) is an herbaceous flowering plant and a member of the family Caryophyllaceae. It is generally distinguished from other species of its genus by "tomentose" or felty foliage. It is a low, spreading perennial native to alpine regions of Europe. The stems & leaves are silvery-grey, whilst the flowers are star-like, white & about 15mm across. [1]
It is an evergreen, creeping off-shoot, perennial, herbaceous plant that reaches heights of growth of 15 to 30 (rarely to 45) centimeters. It is overall densely hairy. The leaves are up to 30 millimetres long and linear to lanceolate, which are covered with silky, silvery, frizzy and entangled hairs, forming like whitish felting. The inflorescences consist of up to 15 flowers. The calyx is 5 to 7 millimetres long. The petals are white and twice as long as the calyx. The teeth of the capsule are slightly bent outwards. The flowering period is from May to July in the northern hemisphere, but may also bloom at other times of the year. [2]
It has proven popular as a cultivated ornamental and can be found in gardens the world over. It is a horticultural plant, perennial, rocky, forming dense silver carpets. This plant is not very demanding: it likes a poor soil, rich in gravel, well drained, in a sunny place. It spreads easily by its rhizomes. [3]
It is native to southern Italy. It is believed to originate from the Caucasus and southeastern Europe. It has naturalised in Canada, the United States and France, where it is often subspontaneous. [4]
Cirsium palustre, the marsh thistle or European swamp thistle, is a herbaceous biennial flowering plant in the daisy family, Asteraceae.
Dianthus chinensis, commonly known as rainbow pink or China pink is a species of Dianthus native to northern China, Korea, Mongolia, and southeastern Russia. It is a herbaceous perennial plant growing to 30–50 cm tall.
Dianthus deltoides, the maiden pink, is a species of Dianthus native to most of Europe and western Asia. It can also be found in many parts of North America, where it is an introduced species.
Ajuga reptans is commonly known as bugle, blue bugle, bugleherb, bugleweed, carpetweed, carpet bugleweed, and common bugle, and traditionally but less commonly as St. Lawrence plant. It is an herbaceous flowering plant, in the mint family, native to Europe. It is invasive in parts of North America. Ajuga reptans is also a component of purple moor grass and rush pastures, a Biodiversity Action Plan habitat in the United Kingdom.
Silene dioica, known as red campion and red catchfly, is a herbaceous flowering plant in the family Caryophyllaceae, native throughout central, western and northern Europe, and locally in southern Europe. It has been introduced in Iceland, Canada, the US, and Argentina.
Jacobaea maritima, commonly known as silver ragwort, is a perennial plant species in the genus Jacobaea in the family Asteraceae, native to the Mediterranean region. It was formerly placed in the genus Senecio, and is still widely referred to as Senecio cineraria; see the list of synonyms (right) for other names.
Pulsatilla pratensis, the small pasque flower, is a species of flowering plant in the family Ranunculaceae, native to central and eastern Europe, from southeast Norway and western Denmark south and east to Bulgaria. It grows from near sea level in the north of the range, up to 2,100 m (6,900 ft) in the south of its range.
Myosotis sylvatica, the wood forget-me-not or woodland forget-me-not, is a species of flowering plant in the family Boraginaceae, native to Europe. This spring-flowering plant and its cultivars, typically with blue flowers, are the familiar forget-me-nots of gardens.
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.
Vinca major, with the common names bigleaf periwinkle, large periwinkle, greater periwinkle and blue periwinkle, is a species of flowering plant in the family Apocynaceae, native to the western Mediterranean. Growing to 25 cm (10 in) tall and spreading indefinitely, it is an evergreen perennial, frequently used in cultivation as groundcover.
Campanula latifolia, the giant bellflower, is a species of bellflower in the family Campanulaceae. It is also known as the large campanula and the wide-leaved bellflower. It is native to Europe and western Asia and is widely grown as an ornamental plant.
Stachys byzantina, the lamb's-ear or woolly hedgenettle, is a species of flowering plant in the mint family Lamiaceae, native to Turkey, Armenia, and Iran. It is cultivated over much of the temperate world as an ornamental plant, and is naturalised in some locations as an escapee from gardens. Plants are very often found under the synonym Stachys lanata or Stachys olympica.
Lysichiton americanus, also called western skunk cabbage (US), yellow skunk cabbage (UK), American skunk-cabbage or swamp lantern, is a plant found in swamps and wet woods, along streams and in other wet areas of the Pacific Northwest, where it is one of the few native species in the arum family. The plant is called skunk cabbage because of the distinctive "skunky" odor that it emits when it blooms. This odor will permeate the area where the plant grows, and can be detected even in old, dried specimens. The distinctive odor attracts its pollinators, scavenging flies and beetles. Although similarly named and with a similar smell, the plant is easy to distinguish from the eastern skunk cabbage, another species in the arum family found in eastern North America.
Salvia farinacea, the mealycup sage, or mealy sage, is a herbaceous perennial native to Nuevo León, Mexico and parts of the United States including Texas and Oklahoma. Violet-blue spikes rest on a compact plant of typically narrow salvia-like leaves; however, the shiny leaves are what set this species apart from most other Salvia, which bear velvety-dull leaves.
Stachys recta, commonly known as stiff hedgenettle or perennial yellow-woundwort, is herbaceous perennial plant of the family Lamiaceae.
Iberis umbellata, common name garden candytuft or globe candytuft, is a herbaceous annual flowering plant of the genus Iberis and the family Brassicaceae.
Digitalis obscura, commonly called willow-leaved foxglove or dusty foxglove or spanish rusty foxglove, is a flowering plant native to regions in Spain and Africa. It is also grown as an ornamental flower. This foxglove is a woody perennial plant belonging to the family Plantaginaceae. Along with the other foxgloves it used to be placed in the figwort family, Scrophulariaceae; however, recent genetic research has moved the genus Digitalis to a larger family. It is similar to many of the foxglove species in its high toxicity and medicinal use as a source for the heart-regulating drug digoxin. Its strikingly distinctive amber- to copper-coloured flowers give the species its name and help distinguish it from other members of the genus.
Festuca gautieri, commonly known as spiky fescue or bearskin fescue, is a species of flowering plant in the grass family, Poaceae, native to the Pyrenees. It is a commonly cultivated evergreen or semi-evergreen herbaceous perennial, and, as a native to European alpine areas, it is a small, low-growing Festuca suitable for rock gardens.
Hypericum hookerianum, or Hooker's St. John's Wort, is a perennial shrub in the flowering plant family Hypericaceae native to eastern and southern Asia. The specific name hookerianum is named for William Jackson Hooker.
Clinopodium menthifolium, commonly known as the wood calamint or woodland calamint, is a species of flowering plant in the mint family, Lamiaceae. It is found throughout southern and central Europe from the United Kingdom and east as far as temperate parts of Asia, and as south as North Africa. It grows up to 1,700 m (5,600 ft) in elevation.
