Q.Fiori Grande Hibiscus
I have recently acquired a Valencia Fiori Grande Hibiscus. It had 5 buds just about to open, but all have dropped off. I have it indoors in a sunny but not hot position. When I received it, it was dry and I gave it a good watering. I would be grateful for any advice you can give me about caring for this plant.
