Aloe castilloniae - An unusual low sprawling aloe that grows as dense cluster to 6 inches tall and spreads slowly over time to several feet wide. The leafy stems are tipped by the 3 inch wide rosettes of 1 inch long recurved and rough textured olive green leaves that have prominent red teeth. Flowering and most growth is put on in fall and winter and going somewhat dormant in the heat of summer. The few orange flowers are held on a very short (about 2 inches tall) simple unbranched inflorescence. Plant in full to part sun in a very well-drained soil and irrigate occasionally to very little - does well with winter rainfall so long as soil drains well. It is not very hardy and often listed as frost intolerant but we have grown it outdoors in our nursery where it has been subjected to light frosts and temperatures down to 31 F. This unique aloe is a bit of a collectors item. Its unusual foliage and clustering habit is the most attractive feature and while the flowers are charming and attractive, they are hardly showy. This rare Madagascan cliff dwelling aloe comes from a location a few miles inland on the coastal facing Plateau Mahafaly near Joffreville in south-west Madagascar where it was found growing on porous calcareous sandstone from 300 to 900 feet in elevation. In the wide it forms almost vine-like stems that hang from cliffs and drape over boulders with stems one to two feet long. It was first described by Jean-Bernard Castillon in 2006 and named to honor his wife Bernadette, a horticulturalist specializing in Madagascan succulents at CB Succulentes on the French Island of La Reunion located in the Indian Ocean. We have a couple clones of this plant and this one is the smaller and tighter of the two, with leaves only about one inch long. We purchased our original stock plant from Cactus and Succulent Society of America Editor Tim Harvey in February 2012.  This description is based on research and observations of this plant as it grows in our nursery, in our nursery garden and in other gardens that we visit. We also incorporate comments received and appreciate getting feedback of any kind from those who have any additional information about this plant, particularly if they disagree with what we have written or if they have additional cultural tips that would aid others in growing Aloe castilloniae.
