Lespedeza cuneata is a species of flowering plant in the legume family known by the common names Chinese bushclover and sericea lespedeza, or just sericea. [3] It is native to Asia and eastern Australia [4] and it is present elsewhere as an introduced species and sometimes an invasive plant. [5]
This plant is a perennial herb with branching stems reaching a maximum height around two meters. It grows from a woody taproot which may exceed one meter in length and which is topped with a woody caudex. The stems are covered densely in leaves, which are each divided into leaflets up to 2.5 centimetres (1 inch) long. Flowers occur singly or in clusters of up to three in the leaf axils. Some of the flowers are cleistogamous, remaining closed and self-pollinating. [3] The open flowers are purple, cream, white, or yellowish in color. [5] The fruit is a legume pod containing one seed. [3]
This plant has been introduced to the United States, South Africa, Brazil, Canada, and Mexico. [5] It was first planted in the US in North Carolina in 1896. It was used to control erosion and to revegetate abandoned mine sites and was used as forage for livestock. It was useful in areas susceptible to drought because its deep roots can keep it alive. A number of cultivars have been developed, including 'Arlington', 'Serala', 'AU Lotan', 'AU Donnelly', 'AU Grazer', and 'Interstate'. [3]
The plant is considered invasive in many areas such as the tallgrass prairie in the Flint Hills of Kansas. [6] When it invades a habitat it reduces the abundance and diversity of native plants and can make the area less attractive to wildlife. It may inhibit the growth of tree seedlings. It may be allelopathic, producing substances that chemically inhibit the growth of other plants. [3] The species also features on the European list of invasive alien species. [7] It is now illegal to sell, transport and breed this plant in the whole of the European Union. [8]
Possible biological pest control agents include the Lespedeza webworm (Tetralopha scortealis). It will probably not be approved for use, however, because it does not discriminate between native and invasive Lespedezas. Grazing may also be a way to control the plant, especially by goats. [3]
At least the following states have restrictions on this plant: Colorado, Kansas, Nebraska, and New York. [9]
The honey locust, also known as the thorny locust or thorny honeylocust, is a deciduous tree in the family Fabaceae, native to central North America where it is mostly found in the moist soil of river valleys. Honey locust is highly adaptable to different environments, has been introduced worldwide, and can be an aggressive, invasive species outside of its native range.
Mesquite is a common name for several plants in the genus Prosopis, which contains over 40 species of small leguminous trees. They are native to dry areas in the Americas. They have extremely long roots to seek water from very far under ground. As a legume, mesquites are one of the few sources of fixed nitrogen in the desert habitat. The trees bloom from spring to summer. They often produce fruits known as "pods". Prosopis spp. are able to grow up to 8 metres (26 ft) tall, depending on site and climate. They are deciduous and depending on location and rainfall have either deep or shallow roots. Prosopis is considered long-lived because of the low mortality rate after the dicotyledonous stage and juveniles are also able to survive in conditions with low light and drought. The Cahuilla indigenous people of western North America were known to eat the seeds of mesquite.
Lespedeza is a genus of some 45 species of flowering plants in the pea family (Fabaceae), commonly known as bush clovers or Japanese clovers (hagi). The genus is native to warm temperate to subtropical regions of eastern North America, eastern and southern Asia and Australasia.
The tallgrass prairie is an ecosystem native to central North America. Historically, natural and anthropogenic fire, as well as grazing by large mammals provided periodic disturbances to these ecosystems, limiting the encroachment of trees, recycling soil nutrients, and facilitating seed dispersal and germination. Prior to widespread use of the steel plow, which enabled large scale conversion to agricultural land use, tallgrass prairies extended throughout the American Midwest and smaller portions of southern central Canada, from the transitional ecotones out of eastern North American forests, west to a climatic threshold based on precipitation and soils, to the southern reaches of the Flint Hills in Oklahoma, to a transition into forest in Manitoba.
Platanthera leucophaea, commonly known as the prairie white fringed orchid or eastern prairie fringed orchid, is a rare species of orchid native to North America. It is a federally threatened species, protected since October 30, 1989 under the Endangered Species Act of 1973. In Canada, it has been listed endangered under Schedule 1 of the Species at Risk Act since 2005. In 2014, the International Union for Conservation of Nature assessed it as "least concern."
Acacia saligna, commonly known by various names including coojong, golden wreath wattle, orange wattle, blue-leafed wattle, Western Australian golden wattle, and, in Africa, Port Jackson willow, is a small tree in the family Fabaceae. Native to Australia, it is widely distributed throughout the south west corner of Western Australia, extending north as far as the Murchison River, and east to Israelite Bay. The Noongar peoples know the tree as Cujong.
Melilotus albus, known as honey clover, white melilot (UK), Bokhara clover (Australia), white sweetclover (US), and sweet clover, is a nitrogen-fixing legume in the family Fabaceae. Melilotus albus is considered a valuable honey plant and source of nectar and is often grown for forage. Its characteristic sweet odor, intensified by drying, is derived from coumarin.
The Manitoba Tall Grass Prairie Preserve is located in southeastern Manitoba near Gardenton and Vita, this is about 50 kilometres (31 mi) south of Steinbach, Manitoba. It is one of the last remaining stands of tallgrass prairie in Manitoba and is part of the Tallgrass Aspen Parkland conservation area in Manitoba and Minnesota. Several groups and organizations help in land preservation in the Manitoba Tall Grass Prairie such as the Nature Conservancy of Canada, Nature Manitoba, Environment Canada, Manitoba Conservation and the Manitoba Habitat Heritage Corporation.
Amorpha canescens, known as leadplant, downy indigo bush, prairie shoestring, or buffalo bellows, is a small, perennial semi-shrub in the pea family (Fabaceae), native to North America. It has very small purple flowers with yellow stamens which are grouped in racemes. Depending on location, the flowers bloom from late June through mid-September. The compound leaves of this plant appear leaden due to their dense hairiness. The roots can grow up to 5 m (16 ft) deep and can spread up to 1 metre radially. This plant can be found growing in well-drained soils of prairies, bluffs, and open woodlands.
Asclepias meadii is a rare species of milkweed known by the common name Mead's milkweed. It is native to the American Midwest, where it was probably once quite widespread in the tallgrass prairie. Today much of the Midwest has been fragmented and claimed for agriculture, and the remaining prairie habitat is degraded.
Lespedeza leptostachya is a rare species of flowering plant in the legume family known by the common names prairie lespedeza and prairie bush-clover. It occurs in the Upper Midwest region of the United States. The flowers are creamy-white to purplish and arranged into a narrow terminal spikes.
Dalea purpurea is a species of flowering plant in the legume family known as purple prairie clover. Native to central North America, purple prairie clover is a relatively common member of the Great Plains and prairie ecosystems. It blooms in the summer with dense spikes of bright purple flowers that attract many species of insects.
Dipsacus laciniatus is a species of flowering plant in the honeysuckle family known by the common name cutleaf teasel. It is native to Europe and Asia. It is present in North America as an introduced species and invasive weed.
Kummerowia striata is a species of flowering plant in the legume family known by the common names Japanese clover and common lespedeza. It is native to much of Asia and it is present in the eastern United States as an introduced species.
Lespedeza bicolor is a species of flowering plant in the legume family known by the common names shrubby bushclover, shrub lespedeza, and bicolor lespedeza. It is native to eastern Asia, ranging from southeastern Siberia to eastern China, Mongolia, Korea, and Japan. and it is widely grown as an ornamental plant. In some regions, such as the southeastern United States, it grows in the wild as an introduced and invasive species.
Eragrostis curvula is a species of grass known by the common name weeping lovegrass. Other common names include Boer lovegrass, curved lovegrass, Catalina lovegrass, and African lovegrass.
Rosa blanda, commonly known as the smooth rose, meadow/wild rose, or prairie rose, is a species of rose native to North America. Among roses, it is closest to come to a "thornless" rose, with just a few thorns at the base. The meadow rose occurs as a colony-forming shrub growing to 1 m (3.3 ft) high, naturally in prairies and meadows. The roses are quite variable, the characteristics such as leaf tip number of prickles and glandular hairs usually do not always remain constant, thus it is often confused with Rosa arkansana or Rosa carolina, the two other prairie rose species.
Lespedeza capitata is a species of flowering plant in the Fabaceae, or legume family, and is known by the common name roundhead bushclover, or roundhead lespedeza. It is native to eastern North America, including eastern Canada and the eastern half of the United States.
