"Australian Tree Fern" Young plants present a spreading canopy of metallic deep green arching fronds supported by a cinnamon trunk; eventually a massive stunning specimen. Although we recommend greenhouse culture in our climate, some customers have successfully grown this as a house or large Wardian Case specimen, always keeping constant levels of humidity. We have grown this to a most impressive size on a sunny porch, glass enclosed during the winter.
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.×
