Gardeners' Notes:


On Aug 22, 2005, gonedutch from Fairport, NY wrote:

I love this plant for its reliable repeat performance in my upstate NY garden. It tolerates the dry conditions of this summer very well. It does, however, benefit from 40 percent shade from morning to mid afternoon (see image). This Hardy Hibiscus seems to have benefitted from the removal of Black Walnut roots that had invaded this area of the garden.
