Fleshy rich green foliage perfect for the large ivory white "Calla Lily" blossoms; best performance in the cool winter greenhouse with ample sun; nonetheless, our customers often grow it in a moist to boggish location in full sun outdoors during the summer and it blooms--a bouquet in your garden! Some plants will simply not read the text books (alone read my meandering pronouncements) . . .
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.×
