|Aloes are a genus of small to large, rosetted, evergreen perennials, with fleshy, sword to lance-shaped leaves, bearing racemes or panicles of tubular or cylindrical flowers. Sap of crushed leaves is used to treat mild burns and sunburns. Aloe polyphylla is stemless, with diamond-shaped, white-toothed, purple-tipped, gray-green leaves, 12 inches long. In the fall, bears pale red flowers, 2 1/2 inches long, on sparsely branched, 20 to 24 inch tall racemes. Grow as a houseplant or under glass, in a soil-based potting mix with added sand or perlite, where temperatures fall below 50 degrees Fahrenheit. Water moderately during the growing season, sparingly while dormant. Sow seed at 70 degrees Fahrenheit or separate offsets in late spring and plant in cactus potting mix.
