"Pencil Cactus" or "Milk Bush" Narrow rounded much-forked stems rapidly grow to form a tree. Used in Tanzania to cure sexual impotence and as a mosquito repellent. (We will not refund for this if, after a year, your child support payments increase dramatically.) Very toxic sap--be sure never to get any sap near your eyes. Still one of the best for a long time specimen houseplant in a sunny window free of children--we know of several situated in low humidity professional offices with little care (but next to a big southern window) that have become magnificent plants over the years.
Some of you grow only indoors, some only in terrariums; many of you have hobby greenhouses; while a growing number of customers live in subtropical or tropical areas of the world. These brief codes are an attempt to suggest whether or not a particular plant will do well in your particular conditions.
If an entry has the cluster HP CGH, this means normal house plant culture will be successful if the plant is given a cool CGH moist location; however if the entry has the cluster CGH HP, you would interpret this to suggest that while Cool Greenhouse conditions are needed for total success with this plant, House Plant conditions will be adequate, while not ideal. If the cluster is HH CGH you would interpret this to mean that while in Zone 8 or below this will be winter hardy outdoor, further north it will need considerable mulch, a cold frame, or a Cool Greenhouse to thrive. And so on.×
