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 ...
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 ...
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 ...
A geophyte (earth+plant) is a plant with an underground storage organ including true bulbs, corms, tubers, tuberous roots, enlarged hypocotyls, and rhizomes. Most plants with underground stems are geophytes but not all plants that are geophytes have underground stems. Geophytes are often physiologically active even when they lack leaves.
Close-up of flower. Brodiaea coronaria is a perennial herb growing from a corm and producing an erect inflorescence with a few basal leaves. The inflorescence is up to about 25 centimeters (10 inches) tall and bears lilylike flowers on an array of pedicels.
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 ...
Chromosome doubling could in principle also create a fertile hexaploid plant. Such a change may be possible via colchicine. [23] Corms of saffron crocus should be planted 10 cm (4 in) apart and in a trough 10 cm (4 in) deep. The flower grows best in areas of full sun in well-drained soil with moderate levels of organic content. [24]
