Tropical hibiscus should be treated as an annual unless you have a nice place to keep them when the temperatures get cold. They can't take a freeze at all and I've never had success over-wintering them outside. My wife, Jo, loves them though and always wants one. She particularly likes the orange ones. This week is her birthday, so when I saw this one at a nursery the other day, it had to come home with me. This variety was developed by Dupont Nursery right here in Louisiana, and it is called "Cajun Orange." It has a lovely "dreamsicle" orange color that doesn't show as well on the computer.
I planted it in this large pot which it will fill out quite well in a couple of months. Hibiscuses can get long and lanky, so I recommend you snip them back once they start getting too tall. They will bloom all the way till frost if you keep them well-watered and fertilized. They must have full sun to thrive.
