It grows into small trees about 10 meters tall in a warm, moist, fertile and well-lit place. Prickly nectary leaf order for pinnately compound leaves, evergreen, leaflet membranous, oblong; flowers pale yellow, a peduncle can result in more than 20 pods; pods mature reddish brown, with seeds 3-6 , One thousand grain weight 306.8 grams, field garden germination rate of about 45%. Under natural conditions, it has a lifespan of about 50 years. The 4-year-old seedlings are flowering and fruiting, with a fruiting period of about 10-15 years.

Thorn clouds are mostly wild, some domestic provinces and autonomous regions have cultivated. The author in the suburbs of Kunming, 1820 meters above sea level after cultivation tests showed that: stab the real demand more fertile, loose, moist, slightly acidic soil, in the red manure-based mountain red soil,
