Gardeners' Notes:

Neutral Nan On Nov 28, 2006, Nan from SW, WI (Zone 4b) wrote:

I've found it difficult to 'pin-down' this plant's needs, but have had success growing it in a very bright facing east window where there is a temperature reduction at night (especially during the winter months.)

Was once told that it prefers more water during summer, so I followed that recommendation and my plant bloomed in November.
