Cherie Hibiscus ~ Tropical or Hardy?

Question

Just bought a Cherie Hibiscus to plant in my yard close to the house on the southeast side from a local nursery. We live in South Central Idaho. Hadn’t planned on digging it up for the winter. Will mulching be enough?

Answer 1

This tropical variety is not cold hardy. Rated for zone 10 and 11.

You will need to bring this plant indoors as soon as the weather cools this fall.
