I think they reseed. Though, I have no idea where you live, and that will be the deciding factor :) Christy

Response to Christy2828. I live in Missouri zone 6. This winter temperatures will get to 0 or below a few times.

Found this...
I need to get some seeds myself and plant them in my bird garden.
The only thing I have in the garden in the summer that the hummers love is the Lucifer (crocosmia) and fushias on my deck in baskets.
I need to add more variety in the garden itself.

Then according to the following site, they are only hardy to 9a. Sorry, they'll probably die off, but they should reseed, so you can grow again next year! Christy

BTW, I have family from St. Louis :)

I am confused, when you say "Hummingbird Vine" is that just a general term for a vine that grows that hummingbirds love or is there such a thing as a Hummingbird Vine?

I am going to grow Honeysuckle vine next year. Alabama Crimson (which is a hybrid of the native Coral Honeysuckle) and is hardy in my zone. Does that mean that this will not resprout on wintered over dormant wood?

Or am I just confused about the vine the OP is talking about?

Thanks all :)
