But it makes me curious, I think I'll buy one
this summer.

You might want to think about whether you have the room
or not. I'm growing a couple of vanilla orchids and they
get very long very fast. I have read that they won't bloom
until they are 20-25 feet long. I have one that is in a
shallow planter, wrapped around and around the planter.
I would estimate it's a good 12-15 feet and still no sign
of a flower, just more vining.
