The genus Ascocentrum is currently one of the most cultivated and popular orchids in the world. It is a plant that is often planted in tropical gardens and requires very little management, which can be used as a potted plant or cut flower. There are about 60 native species in this genus, all of which are epiphytic plants. Widely distributed in the tropical and subtropical regions of the Eastern Hemisphere, from India east to southern China, Southeast Asia, New Guinea, Australia, the Philippines, Solomon Islands and other Pacific islands. Most species have large flowers, bright colors, and long blooming periods, making them very valuable ornamental flowers.
Ascocentrum is a typical epiphytic orchid. Unlike Cattleya and Dendrobium, it is a monopodial orchid with a distinct stem and aerial roots. The roots are sturdier than those of Cattleya and Dendrobium, not only responsible for absorbing water and nutrients but also supporting the stem to stand upright. New roots emerge from the stem in spring, usually white, with the tip of the root cap often green. If the root cap breaks, growth stops. Ascocentrum can attach to other plants or rocks for growth with its sturdy roots.
The flowers are large, usually bright in color, pink, yellow, purple, pure white, and also rare colors in other orchids such as brown, sky blue, etc. The sepals and petals are similar, usually明显 with claws. The lip is adhered to the base of the column, has a spur, 3-lobed, with the lateral lobes erect and the median lobe extending forward; the spur is conical, blunt at the tip, and smooth inside. The column is short, cylindrical, without a column foot, the anther is terminal, 2-chambered, and the pollinia are 2-4, attached to a short and wide, large粘 disk-bearing柄. The leaves are arranged in two rows on the stem, usually three forms can be seen: flat and keel-like on the back; cylindrical; semi-cylindrical with a longitudinal groove on the adaxial side. The leaf surface has a thick cuticle layer, with a strong drought-resistant structure.
Generally, the petals and lips of orchids are well-developed and prominent, but the petals of Ascocentrum hybrids are smaller, the lips even smaller, not obvious, and easily overlooked if not paid attention to. The three sepals are particularly well-developed and prominent, especially the two lateral sepals, which are larger and elliptical, becoming the focus of appreciation. The lip, although in the center of the flower, does not occupy an important position in terms of appreciation. The raceme of Ascocentrum emerges from the leaf axils, with 10-20 flowers, each flower can bloom for 2-3 weeks, usually opening from bottom to top, so each inflorescence can bloom for more than a month under high temperatures.
