Nice article. I'm glad the plantsmen are thinking of small gardens. Haven't had much luck with Clematis but I enjoy growing vines up into small trees, like the annual Dolichos Lablab into a Mimosa...those purple drooping flowers look great against the pale green of the Mimosa, or the delicate perennial Manettia inflata vine up the variegated Willow 'Hakuro nishiki'. The orange-red tiny flowers and small leaves are not too heavy for the Willow stems. Even foliage vines can be attractive like the Asparagus plumosa or the Japanese Climbing Fern because of the lacy light foliage, although they require a fairly sturdy support and look best on a wrought iron porch railing or fence. These are some of my favorites...do you grow many vines? josh
