Caring for Hibiscus
My hibiscus has leaves that are kind of wrinkled looking and the last couple of years it has not bloomed. I keep it in house because every time I put it outside the leaves begin to lose all color and get white, like they are burnt. The wrinkled leaves I believe just started not too long ago.
