Aloe hemmingii is an attractive succulent that forms rosettes of shiny, lime green to dark green or orange leaves with numerous white linear spots. The rosettes have 10 to 15 leaves and grow up to 10 inches (25 cm) in diameter. Flowers are yellow to reddish and appear in spring on an unbranched or few-branched inflorescence. This species is very similar to Aloe somaliensis and often erroneously sold as Aloe harlana by many nurseries and garden centers.
