I don't think height matters, but they need moisture, warmth and lots of sun. I have them clambering up an old tree trunk, stubby and short in a large pot(approximately 5' tall), one trailed in the GH , along a fence, up a pergola and arch and they are various heights. Easy to strike as well from the prunings in the autumn.
So do have a go, they are easy to grow, but need pruning in the autumn to give you fruit. You can use the young leaves too, blanched and stuffed..delicious
