Title: Wintering over a Cuphea ignea in Iowa Zones 4-5
Answered by: Nan Hampton
Cigar plant (Cuphea ignea) is a tropical plant, native to Mexico and the Caribbean. It can withstand light frosts (USDA Plant Hardiness Zones 8-9) and come back in the spring; but, for Iowa in Zones 4-5, I'm afraid it would be 'goner' left outdoors in the winter. It could, however, be grown in a pot as a houseplant and moved outside in its container during frost-free weather to become part of your landscaping.
