Rosa rugosa, Latin scientific name: Euphorbia. Demoulain. Nicknames: Crabapple, Kirin thorn, unicorn flower, Prunus spinosa, Bawangmei, Prunus spinosa, Acacia spinosa, Euphorbiaceae Euphorbia. I like a warm, humid and sunny environment. Slightly resistant to shade, but afraid of high temperature, more resistant to drought, not cold. Humus soil with loose drainage is the best. If the temperature is low in winter, there is short-term dormancy. Widely planted in tropical and temperate regions of the old world; It is cultivated in the north and south of China.
