Depends which Jasmine you mean - Jasmine officinale, for instance, is a twining climber which gets 30 feet high by about 12 feet wide, Jasmine nudiflorum is a lax stemmed "climber" which will need tying onto a framework of wires or a trellis, Jasmine humile is a freestanding shrub and doesn't twine or climb.

And Jasminum parkeri is a 12 inches tall alpine shrublet.

I have a jasmine that's a climber, can't remember the fancy name for it but it's in my 'garden' page!
