Texas landscape resources…and gardenias!

I’ve found the following information useful when determining what to plant in our Texas climate:

I’ve been enchanted with the notion of growing gardenias in the landscape, but worried that the climate might be too harsh here.

Dave’s Garden reports only on the dwarf variety, but a retail source suggests two varieties that are available, the dwarf and a normal height shrub.
