Hibiscus Plant And Fox Glove

Question

Can I leave this hibiscus and fox glove outside for the winter or should I wrap in plant insulation?

Answer 1

Foxglove can, sometimes, survive in zone 7 in ground. In container, it would get too cold and kill the plant. You will want to bring it in to a cool, but not frozen area.

Keep in mind that Foxglove is considered a biennial, or short lived perennial. The first year will be vegetative growth, and the second will be a flowering spike for self seeding before the plants death.

The Hibiscus will depend on the variety. There are several that will be hardy in your area, and several that are not even close to hardy in your area. You would have to consult the place that you got it from to know whether the variety was cold hardy or not. To be sure, you will want to bring it indoors for the winter, and continue care as a HIGH LIGHT requirement houseplant. Even with plenty of light, it will start to enter a semi dormant state. It is going to drop almost all leaves, and turn an ugly yellow until Spring. Just don't prune it until you put it back out in Spring.
