Watsonia meriana is a species of flowering plant in the family Iridaceae known by the common name bulbil bugle-lily. It is one of several Watsonia species known as wild watsonia. It is native to the Cape Provinces of South Africa, [2] but it is well known as an ornamental plant grown in gardens for its showy spikes of flowers, and is an invasive species in areas where it has escaped cultivation.
It is a perennial herb growing from a fibrous-coated corm and growing to a maximum height well over one meter when in flower, sometimes reaching two meters. Each corm produces three or four erect, lance-shaped leaves that measure up to 60 centimeters long by 6 wide. They have thickened midribs and margins. The inflorescence is an open spike of 8 to 25 flowers which may be in shades of orange to reddish or purplish. The flower is up to 8 centimeters long, with a long, tubular throat and spreading tepals.
The flowers sometimes yield capsule fruits which contain seed, but the plant often reproduces via bulbils (strictly speaking, cormlets) that form in clusters in the axils of bracts at nodes along the peduncle. The bulbils can sprout if dropped into the soil, sometimes forming dense colonies, [3] as can sections of corm that are chopped and dispersed by plowing or by non-intensive feeding by root-eating animals. In its native habitat, the plant is valuable as food for local mole-rats ( Cryptomys and Georychus species), and for Cape porcupines ( Hystrix africaeaustralis )
Like some other Watsonia species, in suitable climates, W. meriana can take hold in the wild as a weedy introduced species. It has become habituated along the southern coast of Australia, in New Zealand, on the North Coast of California, on the west coast of Portugal, in Madeira and in Galicia. [4] [5] [6] [7] The plant forms dense colonies that crowd other plant species, and is generally avoided by wildlife as a food source in areas where it is not native. [8]
Corm, bulbo-tuber, or bulbotuber is a short, vertical, swollen underground plant stem that serves as a storage organ that some plants use to survive winter or other adverse conditions such as summer drought and heat (perennation).
Crocosmia, also known as montbretia, is a small genus of flowering plants in the iris family, Iridaceae. It is native to the grasslands of southern and eastern Africa, ranging from South Africa to Sudan. One species is endemic to Madagascar.
Agave attenuata, commonly called the foxtail or lion's tailagave or the swan's neck agave, is a species of flowering plant in the family Asparagaceae. Sometimes called the soft-leaf or soft-leaved agave, the aforementioned animal-related names are a nod to the appearance of the plant's inflorescence, which—after years, generally—rises slightly before gravity brings it back down, giving the bloom a curved, "swan"-like or "foxtail" look. The species' specific manner of flowering is unique in the genus Agave as most other species produce a towering, vertical display, reminiscent of a miniature tree.
Centaurea calcitrapa is a species of flowering plant known by several common names, including red star-thistle and purple star thistle. It is native to Europe but is rarely found there, it is known across the globe as an introduced species and often a noxious weed. The species name calcitrapa comes from the word caltrop, a type of weapon covered in sharp spikes.
Watsonia is a genus of plants in the family Iridaceae, subfamily Crocoideae. Watsonias are native to southern Africa. The genus is named after Sir William Watson, an 18th-century British botanist.
Dipterostemon is a monotypic genus of flowering plants in the family Asparagaceae. Its only species is Dipterostemon capitatus, synonym Dichelostemma capitatum, known by the common names blue dicks, wild hyacinth, purplehead and brodiaea, native to the Western United States and northwest Mexico.
Echium candicans, the 'Pride of Madeira', is a species of flowering plant in the family Boraginaceae, and genus Echium, native to the island of Madeira. It is a large herbaceous perennial subshrub, growing to 1.5–2.5 m.
Dierama is a genus of flowering plants in the family Iridaceae. Common names include hairbells, angel's fishing rod, fairybells, and wandflowers in English and grasklokkies in Afrikaans. They are native to Africa, with most occurring in the southern regions of the continent. The center of diversity is the province of KwaZulu-Natal in eastern South Africa.
Oenothera suffrutescens is a species of flowering plant in the evening primrose family known as scarlet beeblossom and scarlet gaura.
Gladiolus italicus is a species of gladiolus known by the common names Italian gladiolus, field gladiolus, and common sword-lily. It is native to much of Eurasia and North Africa, but it is well known on other continents where it is a common weed, particularly of cultivated fields and waste places. This perennial flower grows an erect stem approaching a meter in maximum height with a few long leaves around its base. Toward the top half of the generally unbranching stem is a spike inflorescence on which flowers appear at intervals. Each plant has up to 15 or 16 flowers. The flower is bright pink to magenta and several centimeters long with its stamens and style protruding from the throat. The fruit is a capsule about a centimeter long containing many seeds.
Berteroa incana is a species of flowering plant in the mustard family, Brassicaceae. Its common names include hoary alyssum, false hoary madwort, hoary berteroa, and hoary alison. It is a biennial herb native to Eurasia and it has been introduced to western Europe and North America. It is listed as an invasive noxious weed in some areas of United States and Canada
Liatris elegans, known commonly as pinkscale gayfeather, pinkscale blazingstar, and elegant blazingstar, is a species of flowering plant in the family Asteraceae. It is native to the southeastern United States as far west as Texas and Oklahoma.
Freesia alba is a species of flowering plant in the iris family. Some sources consider it to be a subspecies of Freesia leichtlinii, F. leichtlinii subsp. alba. It is native to the Cape Provinces of South Africa, but this species and hybrids are known on other continents where they have been introduced. Freesia alba is an herbaceous perennial growing from a corm and producing an erect, often branched stem up to 40 cm (16 in) centimeters tall with several leaves up to about 15 centimeters long. The inflorescence is a spike of several fragrant flowers with usually white tepals marked with yellow and purple.
Ixia maculata is a species of flowering plant in the family Iridaceae known by the common name spotted African corn lily. It is native to the Cape Provinces of South Africa, but it is grown widely as an ornamental plant. It can also be found growing wild as an introduced species in several areas, including Western Australia. This perennial flower grows 20 to 70 centimeters tall with an erect, unbranched stem. There are a few twisting basal leaves up to 35 centimeters long. The inflorescence is a dense, showy spike of up to 12 flowers, usually orange to yellow in color, sometimes with areas of purple or red and often with spots; the coloration in garden plants varies due to breeding.
