Geum aleppicum | |
Geum aleppicum, commonly called yellow avens or common avens [1] is a flowering plant native to most of the temperate Northern Hemisphere, from eastern Europe across Asia and North America.
It is a herbaceous perennial plant growing to 1 m tall with pinnate leaves. The flowers are 2 cm diameter, yellow, with five to seven toothed petals. [1]
There are two subspecies:
It grows in forests and meadows, on grassy slopes, on river banks, in clearings and along roads. [2] [3]
In Europe, it is found in the Carpathians of Romania and Slovakia, in eastern Poland and the Baltic countries, Belarus, Ukraine, [4] the wider Caucasus region and then its area extends from European Russia east across the southern half of Siberia, south up to Tienshan and to the east reaching the Pacific coast, with disjunct distributions in southern Kamchatka, Sakhalin, and northern Japan. [5] [6] It is widespread in the northern temperate region of China, but it can also be found across the central parts of the country and from there southwest up to Yunnan. [3] [6] In North America, its range extends from Alaska through western and southern Canada, most of the US states (except in the southeast), and southwards up to Mexico. [2] [5] It has been introduced in Scandinavia [4] and New Zealand. [5]
Geum, commonly called avens, is a genus of about 50 species of rhizomatous perennial herbaceous plants in the rose family and its subfamily Rosoideae, widespread across Europe, Asia, North and South America, Africa, and New Zealand. They are closely related to Potentilla and Fragaria. From a basal rosette of leaves, they produce flowers on wiry stalks, in shades of white, red, yellow, and orange, in midsummer. Geum species are evergreen except where winter temperatures drop below 0 °F (−18 °C). The cultivars 'Lady Stratheden', and 'Mrs J. Bradshaw' have gained the Royal Horticultural Society's Award of Garden Merit.
Lamium (dead-nettles) is a genus of about 40–50 species of flowering plants in the family Lamiaceae, of which it is the type genus. They are all herbaceous plants native to Europe, Asia, and northern Africa, but several have become very successful weeds of crop fields and are now widely naturalised across much of the temperate world.
The golden samphire is a perennial coastal species, which may be found growing on salt marsh or sea cliffs across western and southern Europe and the Mediterranean.
Lycopodium clavatum is the most widespread species in the genus Lycopodium in the clubmoss family.
Geum urbanum, also known as wood avens, herb Bennet, colewort and St. Benedict's herb, is a perennial plant in the rose family (Rosaceae), which grows in shady places in the temperate regions of Eurasia. It has been introduced in North America, where it forms natural hybrids with Geum canadense.
Calla is a genus of flowering plant in the family Araceae, containing the single species Calla palustris.
Geum rivale, the water avens, is a flowering plant of the family Rosaceae. Other names for the plant are nodding avens, drooping avens, cure-all, water flower and Indian chocolate. It is native to much of Europe, with the exception of Mediterranean areas, as well as some parts of Central Asia and North America. In North America, it is known as purple avens. It grows in bogs and damp meadows, and produces nodding red flowers from May to September.
A bur is a seed or dry fruit or infructescence that has hooks or teeth. The main function of the bur is to spread the seeds of the bur plant, often through epizoochory. The hooks of the bur is used to catch on to for example fur or fabric, so that the bur, which contain seeds, then can be transported along with the thing it attached itself to. Another use for the spines and hooks are physical protection against herbivores. Their ability to stick to animals and fabrics has shaped their reputation as bothersome.
Anthemis arvensis, also known as corn chamomile, mayweed, scentless chamomile, or field chamomile is a species of flowering plant in the genus Anthemis, in the aster family. It is used as an ornamental plant.
Vaccinium uliginosum is a Eurasian and North American flowering plant in the genus Vaccinium within the heath family.
Solidago canadensis, known as Canada goldenrod or Canadian goldenrod, is an herbaceous perennial plant of the family Asteraceae. It is native to northeastern and north-central North America and often forms colonies of upright growing plants, with many small yellow flowers in a branching inflorescence held above the foliage. It is an invasive plant in other parts of the continent and several areas worldwide, including Europe and Asia. It is grown as an ornamental in flower gardens.
Polygonum aviculare or common knotgrass is a plant related to buckwheat and dock. It is also called prostrate knotweed, birdweed, pigweed and lowgrass. It is an annual found in fields and wasteland, with white flowers from June to October. It is widespread across many countries in temperate regions, apparently native to Eurasia and North America, naturalized in temperate parts of the Southern Hemisphere.
Allium textile is a common species of wild onion found in the central part of North America.
Hammarbya paludosa is a small orchid commonly known as bog orchid, bog adder's-mouth or bog adder's-mouth orchid. It grows in bogs in temperate and subarctic regions of the Northern Hemisphere.
Asplenium trichomanes, the maidenhair spleenwort, is a small fern in the spleenwort genus Asplenium. It is a widespread and common species, occurring almost worldwide in a variety of rocky habitats. It is a variable fern with several subspecies.
Artemisia borealis is an arctic and alpine species of plant in the sunflower family, commonly known as northern wormwood, boreal sage, boreal wormwood or boreal sagewort. It is native to high latitudes and high elevations in Eurasia and North America. In North America, it can be found in Alaska, Greenland, the Canadian Arctic, and the Rockies, Cascades, and Sierra Nevada as far south as Arizona and New Mexico. In Eurasia, it is widespread across European and Asiatic Russia and also grows in Scandinavia and in the mountains of central Europe
Sibbaldia procumbens is a species of flowering plant of the genus Sibbaldia in the rose family. It has an Arctic–alpine distribution; it can be found throughout the Arctic, as well as the at higher elevations in the mountains of Eurasia and North America. It grows on tundra and in alpine climates where snow remains year-round, and on subalpine mountain slopes. This is a low, mat-forming perennial herb producing clumps of herbage in rocky, gravelly substrate. A spreading stem up to 15 centimeters long grows from a caudex. Each leaf is divided into usually three leaflets borne at the end of a petiole up to 7 centimeters long. Each wedge-shaped leaflet has three teeth at the tip. The flower has usually five pointed green bractlets, five wider pointed green sepals, and five tiny yellowish petals each about a millimeter long. The fruits develop in the remnants of the sepals on erect stalks.
Vaccinium oxycoccos is a species of flowering plant in the heath family. It is known as small cranberry, bog cranberry, swamp cranberry, or, particularly in Britain, just cranberry. It is widespread throughout the cool temperate northern hemisphere, including northern Europe, northern Asia and northern North America.
Geum reptans, the creeping avens, is a species of flowering plant in the genus Geum of the family Rosaceae native to some mountains of Central and Southeastern Europe. A long-lived perennial that reproduces both sexually and clonally, it has high phenotypic variation, but these variable traits do not appear to be adaptations to local conditions.
