Brassicaceae or Cruciferae is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple, lack stipules, and appear alternately on stems or in rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall.
Yucca is a genus of perennial shrubs and trees in the family Asparagaceae, subfamily Agavoideae. Its 40–50 species are notable for their rosettes of evergreen, tough, sword-shaped leaves and large terminal panicles of white or whitish flowers. They are native to the Americas and the Caribbean in a wide range of habitats, from humid rainforest and wet subtropical ecosystems to the hot and dry (arid) deserts and savanna.
Bitterroot is a small perennial herb in the family Montiaceae. Its specific epithet rediviva refers to its ability to regenerate from dry and seemingly dead roots.
Lunaria rediviva, known as perennial honesty, is a species of plant in the cabbage family Brassicaceae. This hairy-stemmed herbaceous perennial is found throughout Europe. It often grows in damp woods on lime substrates. Growing up to 1 m (3.3 ft) tall, it has large, pointed oval leaves with marked serrations. Clusters of fragrant, pale pink flowers are borne in spring, followed by translucent oval seedheads, often used in flower arranging. It is cultivated as a garden plant, and has gained the Royal Horticultural Society's Award of Garden Merit.
Laburnum, sometimes called golden chain or golden rain, is a genus of two species of small trees in the subfamily Faboideae of the pea family Fabaceae. The species are Laburnum anagyroides—common laburnum and Laburnum alpinum—alpine laburnum. They are native to the mountains of southern Europe from France to the Balkans.
Liquidambar, commonly called sweetgum (star gum in the UK), gum, redgum, satin-walnut, or American storax, is the only genus in the flowering plant family Altingiaceae and has 15 species. They were formerly often treated in Hamamelidaceae. They are native to Southeast and east Asia, the eastern Mediterranean and eastern North America. They are decorative deciduous trees that are used in the wood industry and for ornamental purposes.
The genus Aesculus, with species called buckeye and horse chestnut, comprises 13–19 species of flowering plants in the family Sapindaceae. They are trees and shrubs native to the temperate Northern Hemisphere, with six species native to North America and seven to 13 species native to Eurasia. Several hybrids occur. Aesculus exhibits a classical Arcto-Tertiary distribution.
Lunaria annua, commonly called honesty or annual honesty, is a species of flowering plant in the cabbage and mustard family Brassicaceae. It is native to southern Europe, and cultivated throughout the temperate world.
Lathyrus latifolius, the perennial peavine, perennial pea, broad-leaved everlasting-pea, or just everlasting pea, is a robust, sprawling herbaceous perennial flowering plant in the pea family Fabaceae. It is native to Europe but is present on other continents, such as North America and Australia, where it is most often seen along roadsides.
Nymphaea is a genus of hardy and tender aquatic plants in the family Nymphaeaceae. The genus has a cosmopolitan distribution. Many species are cultivated as ornamental plants, and many cultivars have been bred. Some taxa occur as introduced species where they are not native, and some are weeds. Plants of the genus are known commonly as water lilies, or waterlilies in the United Kingdom. The genus name is from the Greek νυμφαία, nymphaia and the Latin nymphaea, which mean "water lily" and were inspired by the nymphs of Greek and Latin mythology.
Impatiens walleriana, also known as busy Lizzie, balsam, sultana, or simply impatiens, is a species of the genus Impatiens, native to eastern Africa from Kenya to Mozambique. The Latin specific epithet walleriana honours a British missionary, Horace Waller (1833–1896).
Lobularia maritima is a species of low-growing flowering plant in the family Brassicaceae. Its common name is sweet alyssum or sweet alison, also commonly referred to as just alyssum.
Aquilegia vulgaris is a species of columbine native to Europe with common names that include: European columbine, common columbine, granny's nightcap, and granny's bonnet. It is a flowering herbaceous perennial plant growing to 1.2 m tall, with branched, thinly hairy stems. The leaves are biternate; each leaf has three groups of three leaflets. The flowers, in various shades of purple, blue, pink and white, are pendent or horizontal with strongly hooked spurs, and appear in early summer.
A silique or siliqua is a type of fruit having two fused carpels with the length being more than three times the width. When the length is less than three times the width of the dried fruit it is referred to as a silicle. The outer walls of the ovary usually separate when ripe, then being named dehiscent, and leaving a persistent partition. Siliques are present in many members of the mustard family, Brassicaceae, but some species have silicles instead. Some species closely related to plants with true siliques have fruits with a similar structure that do not open when ripe; these are usually called indehiscent siliques.
Poa annua, or annual meadow grass, is a widespread low-growing turfgrass in temperate climates. Notwithstanding the reference to annual plant in its name, perennial bio-types do exist. This grass originated as a hybrid between Poa supina and Poa infirma. Major chromosomal rearrangements after polyploidy have contributed to variation in genome size in Poa annua.
Martynia is a monotypic genus in the Martyniaceae family consisting of a single species, Martynia annua L., which is commonly known as cat's claw, tiger's claw, iceplant. or Devil's claw. However, the name 'iceplant' may also refer to members of the unrelated plant family Aizoaceae.
Persicaria virginiana, also called jumpseed, Virginia knotweed or woodland knotweed is a North American species of smartweed within the buckwheat family. It is unusual as a shade-tolerant member of a mostly sun-loving genus. Jumpseed is a perennial, named for its seeds which can "jump" several feet when a ripe seedpod is disturbed.
Cercis siliquastrum, commonly known as the Judas tree or Judas-tree, is a small deciduous tree in the flowering plant family Fabaceae which is noted for its prolific display of deep pink flowers in spring. It is native to Southern Europe and Western Asia.
Mercurialis annua, annual mercury, is a species of flowering plant in the spurge family Euphorbiaceae. It is native to the Middle East and the Mediterranean region, where it occurs on bare, sandy soils in semi-arid regions. Its seeds are dispersed by harvester ants, which remove an oily coating that delays germination. In recent centuries, annual mercury has spread to northern Europe and many other parts of the world as an agricultural and urban weed. It has been studied for its complex genetics and breeding system. It is named after the Roman god Mercury, due to its association with fertility.
Wisteria brachybotrys, the silky wisteria, is a species of flowering plant in the pea family Fabaceae from Japan. Some older references believed it to be of garden origin. It is certainly very widely cultivated in its native Japan, with the white flowered cultivars more widely grown than the pale violet cultivars. It is in fact native to western parts of Honshu and throughout Shikoku and Kyushu, growing in mountain forests and woods from 100 to 900m. It is not at all clear why it is less popular in the west than in Japan.
