My, my, what a plant! And to think that I spotted it in our small local nursery a few days ago, in West Texas. I didn't know it was a diamond in the rough. Hopefully it grows in rather poor soil. We are zone 6, Maybe someone will tell me if it can survive here. The soil is very alkiline. Thanks for an exciting posting!
I have been growing 2 varieties of Hardy Hibiscus here in southern Kansas for 7 years now and they have done well. Since mine are in full sun all day, the leaves do wilt on the really hot days--in the mid to high 90's---but then perk back up when they are no longer exposed to the sunlight in the evening. Also, on the hotter days, the flower blooms also droop in the heat of the afternoon. In spite of that wilting, they continue to do well overall. They are fantastic plants. I had a yard sale 2 days ago and had several people comment and ask me about them---especially the red one which has been blooming profusely.
Our hardy hibiscus is about 3 years old - we have two, one white and one a beautiful burgundy color. But suddenly this summer, now mid-August, it has stopped blooming and many leaves look like lace.
What can we do to return it to health?
emtsss1950, Your description sounds as tho insects have been munching on the leaves----probably Japanese Beetles. I have had good success with Bayer Rose & Flower Insecticide containing the active ingredient imidacloprid.
