The Q&A Archives: Blue Sky Flower

Question: Durring a recent visit to Florida I was so impressed with the Blue Sky Flower (Thunbergia grandiflora that I purchased one and brought it home to NY. Will it survive the winter? Would it help if I put down a thick layer of mulch just before the firts freeze? Thanks Gene

Answer: This is a tropical plant and will not tolerate cold weather, so although it is a perennial in warm areas such as Florida, you would need to either bring it indoors or replace it each year. A thick layer of mulch would not save it.
