We prefer species clematis to large flowered hybrids; we find they are less fussy and can give just as magnificent a display.  We have a good range of ivy.  Most of these tend to be slow to get going once they have been planted out, but after a few years can cover a sizeable area and look neat and pretty.  Other plants we sell will grow quickly and need space, for example the evergreen honeysuckle, Lonicera halliana, and the large-leaved vine, Vitis coignetiae, which turns a magnificent shade of red in autumn.
