The Q&A Archives: Cold Hardiness of Gardenia

Question: Will gardenias grow in this part of the country? Will they survive all year long and how big do they get? Pam Lennon Mason, OH

Answer: It would be wonderful if gardenias were hardy in cooler climates! Unfortunately, they are not hardy north of Zone 7, as they require mild winters. The cape-jasmine, the most popular gardenia grown in the U.S., is a native of South Africa (it gets its name from the Cape of Good Hope). Have you ever grown one as a houseplant (Gardenia jasminoides)? They demand specific conditions to bloom, but if you are a gardenia lover, it may be worth the effort. Let us know if you are interested in information on indoor culture of gardenias.
