The reason I am asking is that I have been using Space City Hib fertilizer, per their directions, with mixed results. My plants look very healthy and green but the buds are few and far between. We have had an unusual amount of rain, way more than normal, this year and I am wondering if perhaps the plants need a booster to make up for what likely has been washed away.

This is Zelma in still another color phase. This one seems different with each new flower. Her flowers are only lasting one day but it is a young plant; maybe that will change as it matures.
