  • Posted by Baja_Costero (Baja California - Zone 11b) on Oct 23, 2018 3:34 PM concerning plant:
    This giant of the aloe tribe is a thick-trunked, dichotomously branching tree to 30-60 feet with advanced age. Flowers are usually pink. The species was formerly known as Aloe bainesii, but the name barberae was found to have priority in 1994. From southeastern Africa.

    Fast growing for a tree aloe, especially when given regular water. Not generally a good long-term container plant. Unusually sensitive to frost, as aloes go (zone 9b-10a). May be grown from seed (and may be self-fertile); also grown from cuttings. Susceptible to aloe mite (treat by pruning).

    This aloe was recently moved along with a few other tree aloes to a separate genus (Aloidendron) because they were determined by molecular studies to be closely related to each other, and distinct from Aloe. It will be found in older publications as Aloe bainesii. It is one of the parents (with A. dichotomum) of "Hercules", an attractive, fast-growing hybrid which is relatively common in Southern California.
