The shimmery "Black Caladium" with central purple mask between the pale veins of ash silver. Prefers aquatic spot, but successful as regular pot plant, soon forming a colony. Many of you have bought this over the years from us and realize that it has a very long winter dormancy if temperatures stay on the cool side: best left in its container and kept barely moist during this period. However, in a warm greenhouse this beauty will maintain its shimmery foliage.
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.×
