Clematis | Rating: 4 votes | Print / Pdf

The climbing clematis culminates in a crop of colourful clusters! Try saying that after a cupful of cognac!

There are around 300 species of Clematis. They're very popular in gardens with stunning large flowers. Most species are climbing and look beautiful trained up a trellis. Most species are native to China or Japan. They will grow best with cool moist roots and plenty of sun. They'll grow in most types of fertile soil. They are fairly easy to grow but are susceptible to various diseases and also to pests so they can be a little high maintenance. There are loads of different colour varieties, from white to lilac, pink and rich burgundy. The flowers are usually large and star shaped.
