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.
Crocus is an acaulescent (lacking a visible lower stem above ground) diminutive seasonal cormous (growing from corms) herbaceous perennial geophytic genus. [3] The corms are symmetrical and globose or oblate (round in shape with flatted tops and bottoms), and are covered with tunic leaves that are fibrous, membranous or coriaceous (leathery).
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 ...
Iridaceae (/ ɪ r ɪ ˈ d eɪ s i ˌ aɪ,-s iː ˌ iː /) is a family of plants in order Asparagales, taking its name from the irises.It has a nearly global distribution, with 69 accepted genera with a total of c. 2500 species.
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 ...
Corms also bear vertical fibres, thin and net-like, that grow up to 5 cm (2 in) above the plant's neck. [20] The plant sprouts 5–11 white and non-photosynthetic leaves known as cataphylls. These membrane-like structures cover and protect 5 to 11 true leaves as they bud and develop on the crocus flower.
It is left to grow for years and signs that it has enough corms when the mother stems have fewer leaves and it has reached a sizable size with tubers. The harvested corms are cooked for food which is starchy. Unlike taro and eddo, it is not purposely cultivated for its starchy corm for food. It usually grows in the wild in swampy areas and marshes.
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is a form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules.
