Purple Hyacinth Bean Vine

Just how hardy are these vines? I started seeds a bit to early it appears :-) I find myself with 10 gorgeous plants easily 2 feet tall now. Our day temps are in the 50's and 60's, dipping to the 40's in the evenings.
Would they survive if I put them out now?
If not, can they be trimmed back to keep them shorter till temps get warmer?

They'll be fine out now.. It will take a freeze to kill them.. Mine are sprouting all over the place, all over the yard.. I have to spray so many every year because they reseed so bad..They are very pretty, but a pest now for me, lol.. But I just spray a lot and keep a few for my fence..

It got down to 39 last night....I had decided to put one seedling out last night to see how it would fair....it did fine.
I'm gonna plant the others today....I have 4 seeds left, so if something goes wrong (weather wise) I can still sprout a couple more.
Thanks for the reply and the info.

YW,
I've got extra seeds if you need a few more..
