(I) Morphological characteristics: Plants are tall. Stems short. Ye Jisheng, rosette-like, gray-green, inverted lanceolate, up to 1.7 meters long, about 20 cm wide. The thorns of the margins of the leaves are brown initially and later gray, and the thorns of the distal leaves are as long as 3 cm. Calyx stout, up to 8 meters, flowers yellowish green. After the agave flowered and seeded, the rosette died. Pots rarely flower. The cultivars are:
A.a. var.medio-picta: The middle of the leaves has a milky yellow band.
Phalaenopsis agave (A.a. var. marginata-aurea): leaf margins with pale yellow bands.
Silverside Agave (A.a. var. marginata-alba): Leaves margin white or creamy white, with blush when young.
(B) habits: hi warm and dry and well-lit environment, not shade. Strong drought resistance. Hi well-drained, fertile and moist sandy loam, but also suitable for acidic soil.
(C) Cultivation Management: The appropriate growth temperature is 15 ~ 25 °C, the best growth at night 10 ~ 16 °C. Cold and dry winter is most beneficial to its fertility, wintering temperature should be maintained above 5 °C. Compared with hi light, it is often used outside to receive sunlight, but it is necessary for shades of flowers to be properly shaded in the summer to keep the color fresh. In winter, if the light is dark, it should be kept at a low temperature, not watered, and kept dry, otherwise it will rot. Spring should be immediately restored to light. The air humidity is about 40%.
Soil requirements are less stringent, but loose, fertile, well-drained loam is preferred. Potted plants are usually mixed with rot-leaf and coarse sand, and a thin fertilizer is applied for two weeks during the growing season. Watering can be extensive in summer, but drainage should be good. After the fall, water should be reduced, and basin soil should be kept slightly dry.
Change basins every year in April. Be careful to shake off the old roots, cut the dead roots, use pots to loosen the potted soil, and pour a layer of broken tiles. Water should be reduced in the first few weeks and then gradually increased.
(d) Breeding: sowing or propagation. After sowing, it takes a long period of time to achieve the ornamental effect, which is of little practical value. The method of propagation of the ramets is commonly used, usually in conjunction with the douche, that is, in April, the tiller buds around the mother plant are separated and planted separately. After planting, the young plant is placed on the half shade and then moved to a place with sufficient light.
(E) pests and diseases: often harmed by scale insects.
