Professional Growing Information I planted mine in containers early this summer. They grew and performed well on my deck all summer. The blooms were amazing and 8-9 inches wide! They are rather 2 dimensional and blooms parallel to your view are not as noticeable. I was able to turn the containers to face the deck when I was removing the spent flowers. When I wasn’t able to pick up the blooms they got a little messy. The blooms have now finished and the plants are losing leaves. Now I notice that they are infected with white flies. We will probably have our first frost later this week. What is the best method / time to treat these plants for white flies? Will they survive over winter? Thanks

This plant is perfectly named. It is definitely the holy grail of hibiscus! Not only are the flowers themselves absolutely stunning, the leaves are equally striking. The flowers are a rich, deep red, and the leaves are a beautiful purple/dark green color - they complement each other so well! There have been at least 2-3 blooms a day since I planted it 2 weeks ago in mid-late August. It's definitely the show-stopper in my garden. I'll be on the lookout for more at my favorite nursery for sure!

First year gardener and this has outperformed everything! Definitely a show stopper! Absolutely beautiful. So many buds and the flowers are bigger than my head. Just curious if it produces seed pods? They start to turn tan colored then fall off.

I was a little worried when I rec'd this plant, I ordered 2 & one of them was a little messed up in the shipping. I decided to plant it anyways. Boy am I glad I did. It has grown so big & I have lots of buds on it. Can't wait for them to bloom!!! So pleased with it that I just ordered 2 more.
