Aloe marlothii "Utrecht form" (Red Mountain Aloe) - Succulent unbranched large aloe that often grows to 10 feet tall with persistent old leaves making a skirt around the trunk. The leaves of the Mountain Aloe are large, of a gray-green color, with reddish-brown spines along the margins and randomly on other parts of the leaf. In late fall to late winter appears the wide-spread branching inflorescence bearing red flowers this darker color distinguishes this form from the reddish-orange to even orange-yellow flowers of the more typical forms of this species. Plant in full sun in a well-drained soil. Requires little to no supplemental irrigation in coastal California gardens. Hardy to 20 F. The Mountain Aloe is a wide ranging species from KwaZulu-Natal into Mocambique, Zimbabwe and Botswana and there is considerable variability in flower color and shape of the inflorescence. Our plants are from seed resulting from hand pollination of red flowering plants growing in a garden in north San Diego County that originated from seed collected at Utrecht, Kwazulu-Natal, South Africa from a population with many red-flowered plants. Other common names often used for the Mountain Aloe include Spiny Aloe, Flat Flowered Aloe and the Africaner names Bergaalwyn and Boomaalwyn. The specific epithet 'marlothii' honors the botanist H.W. Rudolf Marloth. Aloe marlothii can easily be distinguished from all other single-stemmed aloes by the horizontal (or at least slanted) branching of the inflorescence and the racemes with erect flowers.  Information on this page is based on research conducted in our nursery library, from online sources, as well as from observations made of this plant as it grows in our nursery, in the nursery's garden and in other gardens where we have observed it. We also will incorporate comments received from others and welcome getting feedback of any kind from those who have additional information, particularly if this information is contrary to what we have written or includes additional cultural tips would aid others in growing Aloe marlothii "Utrecht form".
