The classic double blooms are very rich bluey-purple and have a paler mauve bar along the centre of each tepal. The later flowers are single.
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!

Click & Collect
Although we do not open on a regular basis, we are delighted to offer a Click & Collect option for you to collect your orders from our Rails End Nursery location in Worcestershire.
While we get to grips with this new offering we will have to restrict the collection day to a Friday only between 10:00 & 3PM with the hope of expanding that at a later date if we feel it is possible.
Make your online order, checkout and pay online just as if it was a delivery order but of course select Click & Collect instead of a shipping method.
Because we are predominantly a mail order business, our systems are automated and much of the terminology revolves around the kinds of terms used in mail order, so please forgive us for this.
You will receive the following automated emails after making your order.
1. Order acknowledgement. - Full details of your order.
2. Order Status Update - Pending - meaning your order is received into our order processing system

Rails End Nursery
At Thorncroft the quality of our clematis plants is very important to us and we will not compromise on keeping up the high standards our customers have come to expect.
We supply plants mostly in a 3 litre container, growing on a 3 foot (1 meter) bamboo cane support, occasionally a 2 litre pot is sufficient to ensure a quality plant is produced. Your clematis can not always be delivered in full flower, however we will aim to send you the most advanced plant for you so that you get the best display possible in the first year of our plants being in your garden.
Chelsea Chop - Also from time to time we will need to prune plants back to keep them tidy on their cane. While every effort is made to only supply plants in full leaf we may on occasions send plants that have been recently pruned or had leaves removed and will include notes to explain why this has been done. It's known as the 'Chelsea Chop' and is commonly seen in late May and June.
Please keep in mind that some of the more specialist clematis have different habits, so these standards can vary depending on the type you are buying but it gives you a good guide on what to expect.
From the very outset, the Thorncroft philosophy is to provide a clematis which will thrive for the customer in their garden but also to provide the expert knowledge that we have gained over the years to help advise you which clematis are the best.
We have been sending plants by mail order to customers all over the world and have build up a good knowledge of which plants perform best in various parts of the globe. We also value your experience and if would like to tell us about which clematis you grow in your country, please do, it will allow us to continue learning
