Hibiscus schizopetalus: One of my favorite tropical plants to grow in North Texas.
I drag this plant into the garage each winter, right before the first forecast of below-freezing weather. Nestled in the garage for the winter, the hibiscus goes dormant and drops all of its leaves.
Come spring, I drag it outside and prune it back severely. I remove all of the mulch and fallen leaves, top-dress it with earthworm castings and organic fertilizer and add a fresh covering of cedar mulch.
Then I sit back and watch it return to life… And it rewards me with these amazingly delicate blooms all summer long.
schizopetalus literally means split petals.
It is winter hardy in zones 10 and 11. Alas, I garden in zone 8a. I am thankful that hibiscus overwinter very well in this area and remain disease- and pest-free.
I bought my Hibiscus schizopetalus from a local nursery about ten years ago, though they can also be ordered from online suppliers.
