Spring leaves emerge a brilliant yellow gradually fading to a summer green; hybrid of deltoides x nigra resulting in a female form of "Ontario Popular." Seldom variegates in heat of the South; indeed, can fail to variegate even this far north in Ohio if the initial springtime temperatures are too high--especially is night temps are warm. Location. Location. Location. There: truth in advertising. Customers assure us that cutting the trunk(s) down to near ground level mid winter encourages a proliferation of new stems in the spring which are far more likely to show impressive variegation than that produced on older wood.

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.×
