I overwinter in our garage, but of all the hibbies I've ever grown and killed (and there's been MANY), this one is the hardiest. Perhaps, only slightly less hardy than the common red. Highly recommend this one, if you can find it.

Just bought this from Wal-Mart after all our tropical hibiscus were killed by a hard freeze (winter 2010). It will stay in a pot this summer. Quite an unusual bloom as you can see in the photos. We'll see how well it tolerates our 100+ summer heat indexes. Zone 9b.

Dies back in the winter but has never failed to return. I do not cut them back when the freeze comes and they look pretty bad until the spring. Then I cut back the stems until I hit where it was not frozen. I have several now, from woody cuttings in the early summer. Blooms continually from early summer until frost. I cover the roots with pine straw in the winter.

This is one happy hibiscus. Easy to grow and blooms often. It's still blooming (albeit less than in the summer) in my greenhouse where the temp is in the 40's at night.

'El Capitolio Sport' is even more lovely than the original red flowered plant. It is peach colored with deep rose in the center of the outer petals. A flower within a flower is what comes to mind.

Prolific bloomer. Of the Tropical hibiscus, this one seems to be one of the more hardy plants. I grow it in the garden, but I keep potted backups just in case.
