The Victorians with their endless source of labour & insatiable thirst for display, used to grow clematis horizontally in circular beds.
This was achieved by laying suitable sticks within a circular border after careful soil preparation, the plants were then planted between these sticks and carefully trained.
A demonstration is available on the 'Victorian Flower Garden' DVD, with head gardener Harry Dodson.
I have reservations about this being successful with sweet peas.
