The underground part of Huwei Lan has a tough rhizome and no stem. Leaves clustered, fleshy linear-lanceolate, hard leathery, erect, slightly grooved at the base; Dark green, with light green and dark green stripes on both sides, slightly white. Racemes with white to light green flowers with sweet and elegant fragrance; Bloom in spring and summer. Common cultivated varieties are:
Huwei orchid in Phnom Penh: It looks like Huwei orchid, but its leaf edge is inlaid with golden yellow spots.
Crotalaria pigmentosa: It is a dwarf species with a plant height of about 10-20cm. It is a variant of pig excrement bean in Phnom Penh, with short and wide leaves and overlapping growth.
Eupatorium odoratum: also known as Eupatorium adenophorum. The leaves are cylindrical, the thickness of the upper and lower leaves is almost the same, the two ends are slightly sharp, and the leaves are longitudinally shallow, and each leaf grows independently.
Huwei orchid is native to Africa and South Asia, where it has been dry for ten years and is cultivated all over China. Strong adaptability, like warm and humid, drought-tolerant, light-tolerant, and shade-tolerant. The requirements for soil are not strict, and sandy loam with good drainage is better. The optimum growth temperature is 20-30℃, and the overwintering temperature is 65438 00℃.
Eupatorium adenophorum can be propagated by ramets and cuttings. After the temperature rises every spring, the whole plant is separated by changing pots, that is, the whole plant is taken out of the pot, the old culture soil is removed to expose the roots, cut into several plants along its direction, so that each plant contains at least 3-4 mature leaves, and then planted in the pot with new culture soil. Cutting propagation materials are leaves (that is, leaf cuttings), which can be carried out at temperatures above 65438 05℃. Cut the mature leaves into 7-8 cm long pieces and use them as cuttings. After drying a little, insert it into the river sand. Be careful not to insert backwards when cutting; Keep a certain humidity, but not too wet to avoid decay. Adventitious buds and roots can grow from the incision in about a month and grow into new plants. The seedlings of Phnom Penh and variegated leaves are green seedlings, and the Phnom Penh and variegated leaves disappear, which reduces the ornamental value. Therefore, these varieties should not be propagated by cutting leaves, but only by ramets.
Potted Eupatorium adenophorum can be mixed with humus soil and garden soil in equal amount, and a small amount of decomposed base fertilizer can be added as matrix. It grows well in the case of sufficient sunlight, and should receive more sunshine in other seasons except direct sunlight in midsummer. If left indoors in the dark for too long, the leaves will turn black and lack vitality. In addition, if it is kept indoors for a long time, it is not appropriate to suddenly move directly to the sun. It is best to move it to a place with light first, so that it can have an adaptation process, see the sun again and avoid burning the leaves. Water properly, and master the principle that dry is better than wet. Usually use clean water to scrub the dust on the leaves to keep them clean and bright. In spring, when new plants germinate at the root neck, they should be properly watered to keep the basin soil moist; In summer and high temperature season, the basin soil should always be moist; After the end of autumn, the watering amount should be controlled, and the basin soil should be kept relatively dry to enhance the cold resistance. Do not need too much fertilizer, and apply 1-2 times a month in the growing season to ensure that the leaves are green and full.
Huwei orchid leaves are solid and straight, with gray and dark green huwei orchid-like horizontal stripes on the leaves, which are firm and strange and interesting; It has many varieties, great changes in plant shape and leaf color, exquisite and unique; It has strong adaptability to the environment, is a tenacious plant, widely cultivated and used, and is a common potted foliage plant at home. Suitable for decorating study, guest room and office, and can be enjoyed for a long time.
