Q.Non-Blooming Gardenia Plants
I have two gardenia plants in pots in my yard. They seemed to have loved the sun and the leaves stayed beautiful all summer. I only had two flowers in early spring. The plants produced many buds but they fell off before blooming. I want so bad to have blooming, great smelling flowers on these plants!
