Corms can form many small cormlets called cormels, from the basal areas of the new growing corms, especially when the main growing point is damaged. These propagate corm-forming plants. A number of species replace corms every year by growing a new corm. This process starts after the shoot develops fully expanded leaves.
The corms of this lily supposedly resemble dog teeth. [8] Foliage of this plant withers away during the summer. [6] At the end of the stem, the plant produces a white, lily-like flower 3–4 cm (1 + 1 ⁄ 4 – 1 + 1 ⁄ 2 in) in diameter, with six white tepals (3 petals and 3 petal-like sepals) and six yellow stamens.
In gardening, a "bulb" is a plant's underground or ground-level storage organ that can be dried, stored, and sold in this state, and then planted to grow again. Many bulbs in this sense are produced by geophytes – plants whose growing point is below ground level. However, not all bulbs in the gardening sense are produced by geophytes.
Crocus gargaricus is a herbaceous perennial geophyte growing from a corm. It is a small crocus species with bright yellow (occasionally lemon yellow) to orange flowers that commonly has orange, three branched, styles. [4] The corms are small with finely netted, fibrous tunics.
In the United States, Crocosmia × crocosmiiflora is considered suitable for planting in hardiness zones 5–9, but in more northerly locations it can be planted in the spring and the corms dug out in the fall. The corms should be planted in a well-drained garden soil in full sun to partial shade.
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 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 ancyrensis is a herbaceous perennial geophyte growing from a corm. Plants grow 4 to 6 inches tall. [6] The corms are oval shaped with fibrous reticulated tunics. The small flowers are 1 inch long and 0.5 ince wide are orange-yellow with orange-red stigmas. [7]
