A 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).
Iridaceae is a family of plants in order Asparagales, taking its name from the irises, meaning rainbow, referring to its many colours. There are 66 accepted genera with a total of c. 2244 species worldwide. It includes a number of other well known cultivated plants, such as freesias, gladioli and crocuses.
Arisaema triphyllum, the jack-in-the-pulpit, bog onion, brown dragon or Indian turnip, is a herbaceous perennial plant growing from a corm. It is a highly variable species typically growing 30–65 centimetres (12–26 in) in height with three-part leaves and flowers contained in a spadix that is covered by a hood. It is native to eastern North America, occurring in moist woodlands and thickets from Nova Scotia west to Minnesota, and south to southern Florida and Texas.

Lavandula angustifolia, formerly L. officinalis, is a flowering plant in the family Lamiaceae, native to the Mediterranean. Its common names include lavender, true lavender or English lavender ; also garden lavender, common lavender, and narrow-leaved lavender.
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.
Banksia marginata, commonly known as the silver banksia, is a species of tree or woody shrub in the plant genus Banksia found throughout much of southeastern Australia. It ranges from the Eyre Peninsula in South Australia to north of Armidale, New South Wales, and across Tasmania and the islands of Bass Strait. It grows in various habitats, including Eucalyptus forest, scrub, heathland and moorland. Banksia marginata varies widely in habit, ranging from a 20-centimetre (7.9 in) shrub to a 12-metre (40 ft) tree. The narrow leaves are linear and the yellow inflorescences occur from late summer to early winter. The flower spikes fade to brown and then grey and develop woody follicles bearing the winged seeds. Originally described by Antonio José Cavanilles in 1800, further collections of B. marginata were designated as several separate species by Robert Brown in 1810. However, all were reclassified as a single species by George Bentham in 1870. No distinct subspecies have been recognised by Banksia expert Alex George, who nonetheless concedes that further work is needed.
Liatris spicata, the dense blazing star or prairie gay feather, is an herbaceous perennial flowering plant in the sunflower and daisy family Asteraceae. It is native to eastern North America where it grows in moist prairies and sedge meadows.
Liatris chapmanii, also known as Chapman's blazing star or Chapman's gayfeather, is a plant species in the aster family Asteraceae and genus Liatris. It is native to Alabama, Florida and Georgia in the United States, where it is found in habitats such as dunes, beach strands, sand ridges, fields and roadsides, it also grows in longleaf pine savannas and other scrub habitats.
Gladiolus tristis is a species of gladiolus known by several common names, including ever-flowering gladiolus and marsh Afrikaner. It is native to southern Africa, especially South Africa. It is known in parts of Australia and coastal California as an introduced species. It is sometimes grown as a garden plant. This gladiolus typically grows one half to one metre in height, but has been known to approach 1.5 metres tall. It grows from a corm one or two centimetres wide. It produces three narrow, sheathing leaves. The inflorescence is a spike of two to eight large, fragrant blooms. Each flower has six white or cream tepals with greenish or purplish midlines. The flowers are said to have a scent similar to carnations and cloves. Not all individuals possess scent because the allele for its presence is recessive in relation to the allele for its absence.
Lythrum californicum is a species of flowering plant in the loosestrife family known by the common name California loosestrife. It is native to northern Mexico and the southwestern United States into the Midwest as far east as Oklahoma and Texas. It often grows in moist habitat. This is an erect perennial herb reaching 20 to 60 cm tall, sometimes branching. The waxy linear to lance-shaped leaves are arranged oppositely lower on the plant, and alternately toward the top. They are 1 to 7 cm in length. The inflorescence is a terminal spike of flowers with purple petals under a centimeter long. Flowers are heterostylous on one individual plant, with some having long, protruding styles and some with shorter styles not protruding from the mouth of the flower. The fruit is an oval capsule containing many minute seeds.
Persicaria amphibia is a species of flowering plant in the knotweed family known by several common names, including longroot smartweed, water knotweed, water smartweed, and amphibious bistort. It is native to much of North America, Asia, Europe, and parts of Africa, and it grows elsewhere as an introduced species and sometimes a noxious weed.
Tamarix chinensis is a species of tamarisk known by the common names five-stamen tamarisk and Chinese tamarisk or saltcedar. It is native to China and Korea, and it is known in many other parts of the world as an introduced species and sometimes an invasive noxious weed. It easily inhabits moist habitat with saline soils. It may grow as a tree with a single trunk or as a shrub with several spreading erect branches reaching 6 metres or more in maximum height. It has been known to reach 12 metres. It has reddish, brown, or black bark. The small, multibranched twigs are covered in small lance-shaped, scale-like leaves which are no more than about 3 mm long. The inflorescence is a dense raceme of flowers a few cm long. Each fragrant flower has five petals which are usually pink but range from white to red.
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, but it is well known as an ornamental plant grown in gardens for its showy spikes of flowers and an invasive species in areas where it has escaped cultivation.
Costus spicatus, also known as spiked spiralflag ginger or Indian head ginger, is a species of herbaceous plant in the Costaceae family.
Leymus angustus is a species of grass known by the common name Altai wildrye. It is native to Asia and Europe and it is cultivated elsewhere as a pasture grass, especially in Canada.

It is native to parts of Asia and Eastern Europe, and it is known on other continents as an introduced species, including North and South America and Australia. It is a weed, invasive at times.
Gladiolus watsonioides is a medium to high (½–1 m), herbaceous geophyte with sword-shaped leaves, flattened in the plain of the stem, and spikes of red funnel-shaped flowers, that is assigned to the iris family. In the wild, the species is restricted to the highlands of central Kenya and northern Tanzania, including on Kilimanjaro, Mount Kenya and the Aberdare Range. It is sometimes called Mackinder's gladiolus.
