Flower Gardening Tips : How to Grow Common Heliotrope (Heliotropium Arborescens)

Thanks Alberta for the comment. Zone 9 on the West Coast is temperatures down to 20 to 30 degrees so if mulched well thay can handle a short freeze. When you google heliotrope zones will show anywhere from 7 to 12. In the NW we can mulch them well and they should survive.

Yolanda the heliotrope looks wonderful. However I want to know what you mean by Zone 9 and what kind of climatic zone system you are using. Because I realize the Columbia valley is simply too cold for these plants. The Sunset Western Garden book says that the coldest possible place for these plants is zone "15". This is the coast range of California and its northern extremity is Klamath.
