In botany, a bulb is structurally a short stem with fleshy leaves or leaf bases that function as food storage organs during dormancy.
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).

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.
Leucanthemum maximum is a species of flowering plant in the aster family known by the common name max chrysanthemum.
Odontostomum is a monotypic genus of flowering plants containing the single species Odontostomum hartwegii, which is known by the common name Hartweg's doll's-lily. In the APG III classification system, it is placed in the family Tecophilaeaceae. It was formerly placed in the Liliaceae. It This wildflower is endemic to northern California, where it can be found in the inner coastal mountain ranges and the Sierra Nevada foothills. It grows in rocky clay and often serpentine soils in grassland and woodland habitat, sometimes near vernal pools. This is a perennial herb growing from an oval-shaped corm up to 3 centimeters wide deep in the soil. The curving, widely branching stem is up to about half a meter in maximum height with linear leaves up to 30 centimeters long sheathing the lower portion. The inflorescence is a raceme or panicle of several flowers on pedicels. Each flower has six white or yellowish tepals, the lower parts fused into a veined tube and the tips spreading and then becoming reflexed. At the center of the flower are six stamens and six staminodes in a ring around the gynoecium.
Oenothera wolfii is a rare species of flowering plant in the evening primrose family known by the common name Wolf's evening primrose. It is native to the coastline of southern Oregon and northern California, where it grows in coastal prairie, dunes, and coastal forest and woodland habitat. As of 1997 it was known from only about 16 occurrences. The biggest threat to the plant is its easy hybridization with its relative and probable descendant, Oenothera glazioviana. As this rare wild plant crosses with the introduced garden escapee, introgression occurs, causing what is known as genetic pollution; fewer pure individuals of O. wolfii will be seen as they are outnumbered by hybrids.
Phyla lanceolata is a species of flowering plant in the verbena family known by the common names lanceleaf fogfruit, fogfruit, or frogfruit. It is native to the southern half of North America, including much of the United States except for the northwestern quadrant, and much of Mexico. It is resident in many types of moist and wet habitat, including disturbed areas, such as irrigation ditches. It is a perennial herb growing decumbent in a matlike form with spreading, trailing stems up to half a meter long, sometimes rooting at nodes. The lance-shaped or nearly oval leaves are up to 6 centimeters long and have toothed or partially toothed edges. The inflorescence, arising on a peduncle several centimeters tall, is a spherical spike of flowers which elongates into a cylindrical form as the fruits develop. The tiny, densely packed flowers are white, sometimes tinged with blue or purple.
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.
Watsonia marginata is a species of flowering plant in the family Iridaceae known by the common name fragrant bugle-lily. 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. Its native range is an area with winter rainfall and dry summers. It is a perennial herb growing from a corm and growing to a maximum height well over one metre when in flower, sometimes reaching two metres. Each corm produces three or four erect leaves that measure up to 80 cm long by 5 wide. They are blue-green with thickened yellow margins. The inflorescence is a dense spike of 30 to 50 flowers which may be any shade of pink or sometimes dark red or white. The flower is actinomorphic, or radially symmetrical, unlike those of other Watsonia, which are zygomorphic. The flowers are several cm long.
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.
Liatris ohlingerae is a rare species of flowering plant in the aster family known by the common names Florida blazing star, Florida gayfeather, scrub blazing star, and sandtorch.
