I am looking for a companion planting to center a group of gaura lindheimeri, and I was thinking that a hibiscus with deep pink flowers might be just the ticket. (The gaura is pale pink and blooms in late summer/ early autumn.)
So, now I'm wondering: (a) Would it be foolhardy to try planting hibiscus in the fall here? (b) How much water does hibiscus really need here in the semi-desert? and (c)Can anyone recommend a tried-and-true cold-hardy variety that comes in a deep or clear pink?
