There is a fair amount of information out there on this very special plant, sometimes referred to as Drakensburg Aloe (or more commonly Spiral Aloe) so I won’t go into all the details. Aloe polyphylla has become more readily available since the advent of tissue culturing difficult-to-propagate plants. Tissue culture is the propagation of plants as “test tube babies” or cloning. For plants that seldom flower, or require many years to reach flowering maturity, tissue culture is used to speed up the process. Plants that might not come true from seed, or are not easy to propagate from cuttings are also good candidates for tissue culture.
I have had the good fortune to work with Alan Beverly, http://www.ecotree.net, an expert in the understanding of this plant. Alan brought seed from South Africa for Aloe polyphylla many years ago, before this plant made the endangered species list, and has produced numerous seed crops over the years.
When tissue cultured plants began to appear in the market place, I had this idea that I would buy plants from several different labs. I would then grow the plants to maturity, along with seedlings I had purchased from Alan and then cross pollinate the different plants to produce seedlings of my own. I now have several hundred plants approaching maturity and hope to have flowers in the next year or two; then the fun can begin!
What I did not anticipate is how different the tissue cultured plants would be compared to the seed-grown plants. Aloe polyphylla from seed develops a more defined spiral form at a much younger age. My conclusion, after watching these plants for about six years: if given the option, buy the seed propagated plants.
We just purchased over one hundred of Alan’s seedlings to offer for sale at Succulent Gardens. There are both left and right spirals. When you buy this plant, know which you are buying, because the wow-factor is quite different between seedlings and tissue cultured plants. I am told by one reputable grower that in the long run, the tissue cultured plants will fully develop. I just don’t know how long that run is.
