Mandevillas are a tropical vine and won't survive the winter outside here.( I live in Zuni from the Beach )You could look into Trumpet vine. Theres a red flowered one and one with yellow flowers thats pretty cool.

Good luck! Eric

I plant mine in a pot about 18in wide and 18in high. then in the fall after first frost, i cut the vines back and keep them in my green house and put them back in spring (just did in fact on 4/21/08). my neighbor puts them in a sparebath room by a window. mandevillas grow very fast so its no big deal to cut them back and/or replant in the spring.

wieltom, how well do they bloom the next season? I've tried wintering over and they just sort of sit there the next season.
