Is one of the best rootstocks for grafting Yunnan camellia. It has the characteristics of strong affinity, high survival rate and good growth potential. In the past when the cutting, the matrix with a mixture of laterite and leaf mold, rooting slowly (usually up to more than six months), the survival rate of only 50-60%, 3-4 years of culture before becoming a rootstock.
