Northern Chinese "Fountain Hardback" a cascade-branched shrub with attractive dusky pewter toned oval leaves which change to a charming rich butter yellow fall color range; small lime flowers (which confirm it to be in the spurges) line long peduncles late summer. If you grow hardy Euphorbia in your gardens, why not plant this spurge shrub as a thematic backdrop? If the stems become too large, simply stool the stems down to ground level to encourage a perfect whiskbroom of slim stems to emerge the following spring. From Arnold Arboretum seeds distributed by its most devoted fan, Gary Koller.
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.×
