    Clumping Tanzanian aloe with glossy light green leaves that can turn bright orange-red to scarlet in full sun or in response to stress. One of the best aloes for red color. Flowers may be red or yellow, with greenish tips when they open. Plant in full sun for best color in mild climates. Very frost sensitive.

    This species has absorbed A. harmsii (yellow flowers). It can be distinguished from the Tanzanian A. bussei (pink flowers) based on a few features: the teeth on dorotheae are somewhat harder; the inflorescence is usually simple, not branched; the racemes are shorter; the floral bracts and pedicels are shorter. All 3 species were described by Berger in 1908.
