A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: Can Carolina jessamine be grown in Syracuse NY?
Answered by: Barbara Medford


Hi--Can Carolina Jessamine be grown in Syracuse, New York?


Gelsemium sempervirens (evening trumpetflower) is native to North America, in the Southeast and as far west as Texas. It is hardy in USDA Hardiness Zones 7 to 9; Syracuse is Zone 5b. This Floridata site states that it can withstand light frosts, but protracted freezing will kill it.  You would have jessaminecicles. Sorry.
