These plants are wrapped in bird netting - up to, or near, the top leaves.
I found the grow-through supports to be too short, so the top section of these are also wrapped in bird netting. (The blooming ones, on the right)
These are growing through a sectioned support that you can usually find at garden centers or the big box stores. Get the taller ones unless you know you have very short-growing plants (you can push them in deeper if they're too tall).
I've also enclosed entire groupings in 28" tall sectioned garden fence. It must not have been very attractive, however, since I can't find a picture of it.
It worked well, but it was white - I would have preferred a dark green.
