What are the common ornamental species of nail orchid?

There is no pseudobulb in this genus, because the leaves are mostly leathery or nearly cylindrical, they have strong drought tolerance. And the aerial root is well developed, and some water and nutrients can be obtained from the moist air. The suitable temperature for growth is 18 ℃ ~ 30 ℃, and more than 10 ℃ can survive the winter safely. The demand for light is slightly higher, prefer more than medium light, 50% shade in summer and autumn, and full light in spring and winter. Because there is no false bulb, it is impossible to store a lot of water, so the substrate should be kept moist during the growing period, and spray moisturizing to the plant to prevent the air from being too dry and losing water. Cultivation should choose epiphytic substrate pot, can also be tied to the trunk, snake wood maintenance. Applying balanced fertilizer 1500 times once a month during the growing period, and increasing the amount of phosphorus and potassium fertilizer during flower bud differentiation was beneficial to plant flowering. It is difficult to tiller, sometimes a small number of high buds can be cut off and planted elsewhere, and the medium sowing method can be used for propagation.

1. Nail orchid (Aerides falcata)

Epiphyte of southeastern Yunnan. Born on a tree trunk in a mountain evergreen broad-leaved forest. It is also distributed in Southeast Asia. Stem stout, with several distichous leaves. Leaves banded, racemes sparsely several flowered, sepals and petals pale white, distally purplish red; labellum 3-lobed. The florescence is from spring to summer. Suitable temperature for growth is 20-28 ℃, like good ventilation environment, easy to cultivate, like medium light.

two。 Polygonum multiflorum (Aerides rosea)

Epiphytic herbs, produced in Guangxi, Guizhou, Yunnan and other places. Born on tree trunks of mountain forest margins or sparse evergreen broad-leaved forests on slopes at 320-1530 m above sea level, also found in Southeast Asia. Stems stout, leaves fleshy, narrowly oblong or banded. Inflorescence leaves axillary, densely many flowers; flowers white with purple spots, spreading; labellum 3-lobed; front of lateral lobes dark purple; middle lobe densely covered with purplish red spots near above; spur white; core column white with purplish red. Capsule subovate. Flowering in July and fruiting in August to May of the following year. The suitable temperature for growth is 18 ℃ ~ 28 ℃, easy to cultivate and prefer medium light.

3. Fragrant flower nail lily (Aerides odorata)

Epiphytic herbs with stout stems from Guangdong and Yunnan, born on tree trunks 200-1200 m above sea level, as well as Pakistan, India, Indonesia, Laos, Myanmar, Malaysia, Nepal, Philippines, Thailand and Vietnam. Leaves thickly leathery, broad-frequency, apex obtuse and unequilateral 2-lobed. Racemes pendulous, subequal or longer than leaves, densely many flowers, flowers large, spreading, fragrant, white and pinkish, labellum inserted at end of core column, 3-lobed, lateral lobes erect, larger, apex obtuse, upper margin with irregular teeth, middle lobe narrowly oblong, spur narrowly angled. Flowering in May. The suitable temperature for growth is 18-30 ℃, which is easy to cultivate and should be maintained in a slightly shaded place.

4. Nail lilac (Aerides mitrata)

Epiphytic herbs with short stems, Thailand and Myanmar, epiphytic on the trunk of the rainforest. Leaves strip-shaped, subcylindrical, margin rolled inward, leathery, green, margin entire, stem with a large number of aerial roots. Racemes erect or obliquely extended, shorter than leaves, densely numerous flowers, flowers small, white with pale pink, lips and core column pink. Flowering in spring. The suitable temperature for growth is 20 ℃ ~ 30 ℃, and it is not cold-resistant. It can be planted in the shade or attached to the trunk for cultivation and maintenance. It is named because the leaves of this species are nearly rod-shaped. This species was classified as Seidenfadenia mitrata when it was published by Mr. Reichenbach in 1864. Because its half-stick-shaped leaves are completely different from other plants of the genus Nymphaea, in 1972, Mr. Seidenfaden divided it into its own genus, and named it as Cymbidium. The species word mitrata continues to be used, and the word means monk's hat, and the Chinese name should be "monk's cap".
