Types of COLD HARDY hibiscus zone 7a?
Your best bet is a Mallow Hibiscus or Texas Star Hibiscus. I live in Zone 7 and have 5 of them. This year they grew over 5 feet tall and wide. They love full sun, and a lot of water.



The Texas Star is Red, and Mallow comes in Red, White, Pink and a White flower with Red tips.
Reply:I'm in zone 5, and I have the Lord Baltimore variety. 4 year old plant, 13 stems this year, about 6-8' tall. Ask at your local garden center, NOT HOME DEPOT! I don't think you'll find one now, but in the spring there will be plenty.



There are many hardy varieties, with many different colors. You might want to add a Rose Mallow. It is a smaller version of hibiscus. Or, a Rose of Sharon tree. Small, beautiful bloomer. All of these do well in my zone 5
Reply:There are two basic types of hibiscus: a true tropical and a perennial.



The perennial hibiscus varieties are the hardiest. But, they are still very susceptible to cold temperatures (a hibiscus, after all, is a tropical plant). It dies if exposed to temperatures below freezing. Below the low 40s, it will lose its leaves, but just go dormant. Below the mid 60s, it will grow leaves, but will probably not bloom.



A true tropical hibiscus is the kind with the showiest flowers that can get up to the size of a dinner plate. But, they are even more susceptible to cold temperatures. They won't even flower if the temperatures don't get above about 70 degrees during the day.



In areas that get below freezing in the winter, a hibiscus plant must be potted and brought indoors to a sunny location. Even then, it may not bloom or even grow any new foliage until spring.



Also, when you bring the plant indoors, you should not water it nearly as much as when it was outside. When the plant slows its growth, it doesn't need much water. Overwatering or letting it sit in standing water (in a saucer, for example) will cause root rot and kill the plant.
