Q. Who is Mr. Smarty Plants?

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: Non-native tropicals for Syracuse, NY
Answered by: Barbara Medford

QUESTION:

I live in upstate New York but am a fanatic about tropical plants, palms and banana trees. They're obviously all in pots that I take indoors, and I lose them from time to time. (Had a coconut palm that lasted 13 months - I don't know how.) Is there any tropical tree that I could actually grow outdoors to impress the neighbors? I think I'm in Zone 5b.

ANSWER:

The expertise at the Lady Bird Johnson Wildflower Center is exclusively that of plants native not only to North America but to the area in which the plant is being grown. Your situation proves our case. A plant native to New York would be able to survive outdoors because it has adapted over eons of experience to the climate, rainfall and soils of that area. There are non-native tropicals that can be grown in South Florida, Texas and California, but not Zone 5a to 5b, where Onondaga County is. With average annual minimum temperatures of -20 to -10 deg. F, it is unlikely that a tropical plant could even survive nighttime summer temperatures. Most tropicals are considered adaptable to Zones 10 to 11. You are certainly free to grow and enjoy whatever plants you like, but there is no way to alter the natural requirements of a plant. Continuing to grow those plants indoors is really your only choice.
