I grew a Cardinal Vine from seed this year for the first time, and it is not blooming yet. It is quite healthy and climbing quite well, but no blooms. When do they bloom?
I have Cardinal Vine and mine haven't bloomed either. They love the heat but we might be getting a little to much for them to set blooms. Mine are usually covered in blooms by now.
Well, phooey. Planted close to HB feeder and was hoping to give the birds a little treat! Thanks for your response.
