"Blue Taro" Purple stems arch into swooping arrowhead leaves of dusky violet darkening to a rich purple toward the margins; this West Indian semi-aquatic "Blue Ape" must have warm winter conditions to maintain evergreen foliage; easiest to grow as a semi-aquatic in summer (but very successful as a container companion plant or even planted in a bed with some perfect color companion like 'Lime Zinger'): then store like a dormant "Elephant Ear" during the winter. And like all Colocasias and Xanthosomas, most successfully stored by leaving them in their containers so that their ever so slightly moist undisturbed potting mix is around them all winter to prevent drying out and rot. Nonetheless, reliably evergreen [everpurple] in your winter greenhouse or warm plantroom.
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.×
