Small shrubby tree with dark minutely hairy leaves which, when bruised, give off a stong licorice/anise fragrance. Good container plant for sunny location, easily shaped and sheared to compact shapes and even tolerating temps in the upper 40s mid winter when it produces many tiny Lantana-like heads of blossoms. This important Asian herb needs adequate humidity to avoid developing a case of red spider infeststion--so (as with "Lemon Verbena") best considered a sunny greenhouse plant rather than a house subject. (Nonetheless, customers tell us it if far easier than we suggest.)
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.×
