Crocus (/ ˈ k r oʊ k ə s /; plural: crocuses or croci) is a genus of seasonal flowering plants in the family Iridaceae (iris family) comprising about 100 species of perennials growing from corms. They are low growing plants, whose flower stems remain underground, that bear relatively large white, yellow, orange or purple flowers and then ...
Brodiaea species are herbaceous perennials, growing from corms. Between one and six narrow leaves are produced from the corm. The bare flowering stem carries an umbel of flowers. Individual flowers have six blue to purple tepals, joined at the base to form a tube with free lobes at the mouth. The outer three tepal lobes are narrower than the ...
A number of species replace corms every year by growing a new corm. This process starts after the shoot develops fully expanded leaves. The new corm forms at the shoot base just above the old corm. As the new corm grows, short stolons appear that end with the newly growing small cormels. As the plants grow and flower, they use up the old corm ...
The plant blooms annually around the beginning of the rainy season. The flower bud emerges from the corm as a purple shoot, and later blooms as a purple inflorescence. The pistillate (female) and staminate (male) flowers are on the same plant and are crowded in cylindrical masses as an inflorescence. The top part is responsible for secreting ...
Colchicum (/ ˈ k ɒ l tʃ ɪ k əm / KOL-chik-əm or / ˈ k ɒ l k ɪ k əm / KOL-kik-əm) [2] is a genus of perennial flowering plants containing around 160 species which grow from bulb-like corms. It is a member of the botanical family Colchicaceae , and is native to West Asia , Europe , parts of the Mediterranean coast, down the East ...
They are herbaceous plants which grow from a conical corm1–2.5 cm (1 ⁄ 2 –1 in) diameter, which sends up a tuft of narrow leaves 10–30 cm (4–12 in) long, and a sparsely branched stem 10–40 cm (4–16 in) tall bearing a few leaves and a loose one-sided spike of flowers with six petals.
Oxalis triangularis grows from corms (also called "bulbils" [4]), propagated by division. Like other corms, it goes through regular dormancy periods; at the end of each period, the corms can be unearthed, offsets cut and replanted in appropriate soil, where they will grow into new plants. [10]
Growing to 18 cm (7 in) tall by 10 cm (4 in) wide, it is an herbaceous perennial growing from corms. C. speciosum blooms in the fall, producing reddish/violet flowers on stems up to 30 centimetres (12 in) tall without any leaves present. The strap-like leaves grow in the spring, then yellow, wither and die back as summer progresses.
