Misc FactsThe size and number of flowers of this plant depends to a great extent on the growing conditions. The ones I have grown, usually fend for themselves. Will give additional water when needed. I drive past a planting of hardy Hibiscus where the gardener has supported the plants with a low decorative fence and waters on a regular basis. These plants are twice the size of mine with double the amount of flowers. A stunning display for their garden.
Author's NotesPlants are hardier than many people think. In one of the coldest winters (2014) not one of my plants died and only lost a few at the garden center. In zone #5 they are very slow to emerge, I seem to get 3-5 years of life from these plants.
