Large flowered clematis prefer a good quality soil with high nutrient levels and a soil which is moist but free-draining. Improve planting holes with at least 2 forkfuls of well rotted manure or garden compost and if you don't have these use a 'Soil Improver' compost. The Improvement material added should be placed under the root of the plant not around it. This encourages the roots to grow downwards and remain deep and cool during summer. If your clematis flowers in May-June(late spring), cut the dead flower heads when they have finished to encourage a second set of flowers to be produced in the late summer and autumn. Be prepared to wait for a couple of years before they will be at their best - Our saying is - 1st year = Roots, 2nd year = Shoots, 3rd year = Flowers!

Cannot recommend highly enough. I ordered a number of plants recently from Thorncroft, which all arrived in excellent condition. They were very well packaged and arrived promptly, still upright in their pots. The plants are also super specimens.

We saw this plant at Chelsea and was bought as it was the name of our pet dog. This year it has been beautiful and made me smile each time I pass as Kaiser was with me when I planted it. Stunning and many friends have commented on the display.
