Angraecum humbertii is native to Madagascar, , where it grows in the province of Toliara at elevations of 500 to 999 m above sea level. This epiphyte grows in subarid thickets, inselbergs or rock faces and anthropic areas.
Angraecum humbertii also called as Humbert's Angraecum, is a species of the genus Angraecum. This species was described by Joseph Marie Henry Alfred Perrier de la Bâthie in 1939.
IDENTIFY ANGRAECUM HUMBERTII ORCHID PLANT
Angraecum humbertii is native to Madagascar, where it grows in the province of Toliara at elevations of 500 to 999 m above sea level. This epiphyte grows in subarid thickets, inselbergs or rock faces and anthropic areas.
It is a small sized, warm growing lithophyte with a short, thick, slightly compressed stem carrying 2 ranked, broadly linear to loriform, often conduplicate, leathery, slightly glossy, very unequally bilobed apically, lobes rounded, basally clasping leaves.
Humbert's Angraecum blooms in the late spring and early summer on a robust, 20 cm long, 4 to 8, successively flowered inflorescence with 2 to 3, acute sheaths and a very thin floral bract. The flowers greenish-white with the labellum pure white.
ANGRAECUM HUMBERTII ORCHID PLANT CARE AND CULTURE
Cultural information should only be used as a guide, and should be to be adapted to suit you. Your physical location; where you grow your plants, how much time you have to devote to their care, and many other factors, will need to be taken into account. Only then can you decide on the cultural methods that best suit you and your plants.
Light:
Angraecum humbertii needs a light level of 20000-30000 lux. Light should be filtered or diffused, and plants should not be exposed to direct midday sun. Strong air movement should be provided at all times.
Temperature:
Summer days temperature average 29-30°C, and nights temperature average 18-19°C, with a diurnal range of 11-12°C.
Humidity:
Humbert's Angraecum need the humidity of 70-75% in summer and autumn, dropping to 60-65% for about 3 months in late winter and early spring.
Substrate, growing media and repotting:
Angraecum humbertii grow better if mounted on slabs, but they may be potted if care is used. If mounted, high humidity must be maintained and the plants watered at least daily during hot, summer weather. If potted, a very open, fast draining medium such as medium to large fir bark or cork nuggets is recommended. Undersized pots large enough to hold the roots should be used, and repotting should be done just as new root growth is starting, or as soon after flowering as possible.
Watering:
Rainfall is moderate to heavy from late spring to early autumn. Averages then drop rather abruptly in mid-autumn at the beginning of the dry season, that lasts about 5 months until late winter or early spring. Cultivated plants should be watered heavily while actively growing, but drainage must be excellent. Water should be reduced in autumn after new growths mature.
Fertilizer:
1/4-1/2 recommended strength, applied weekly when plants are actively growing. You can use a balanced fertilizer throughout the year; but also can use a high-nitrogen fertilizer from spring to midsummer, then switch to one high in phosphates in late summer and autumn.
Rest period:
Winter days temperature average 24-26°C, and nights average 12°C, with a diurnal range of 12-14°C. Angraecum humbertii plants need much less water in winter, but plants should not be completely without water for long periods. Occasional early-morning misting between infrequent light waterings should be adequate in most growing areas. Water should be increased somewhat if leaves shrivel or show signs of stress. Fertilizer should be eliminated until new growth starts and heavier watering is resumed in spring.
