The Q&A Archives: Trumphet Vine

Question: Hi, My name is Dee I really enjoy this site ,as I enjoy Plants of all kinds . My question is ..Last year I grew a trumpet vine from seeds ,by surprise it grew in a pot on the front porch, are these preannuals,do they come back to life if left out side?

Answer: Trumpet vine or Campsis radicans is a very cold hardy (and heat resistant) perennial vine and actually becomes woody with age. In my experience it will survive in at least zone 6 in a large container; container plants tend to be a bit less hardy because their roots are not insulated down in the ground the way they normally would be. The larger the container and the more sheltered the spot, the better its chances. If the pot is a small one you could heap mulch around it or insulate it in some other way. Be patient in the spring, this vine tends to start growing late a bit in the spring season. Also, I should note that there are quite a few other plants sometimes called trumpet vine, or with trumpet shaped flowers, and many of them would not be hardy, they would have died with the first freezes or for the half hardy types, probably by the time the temperature hit about 20 degrees. Good luck with your vine!
