hibiscus outside in RI
I have a few hibiscus plants inside and want to put them into my outside garden here in Newport, RI Suggestions, please
There are 2 types of hibiscus common in US gardens. One is tropical and is not hardy in Rhode Island. It enjoys outdoor conditions in the summer, though. The other is a shrub up to 15' tall, Hibiscus syriacus. It is hardy north to zones 4 or 5 depending on the specific cultivar. Rose mallow is also in the Hibiscus genus, a large group in the mallow family.
