Cultivation Information

This eye-catching clematis has rich deep pink trumpet shaped flowers with paler mauve-pink margins. A 'classy' addition for your garden.
A plant that we always have in our garden. The blooms are just delightful and carry on well into the autumn giving a long period of interest for the gardener.
'Princess Diana' is also a fantastic companion plant growing very well with roses and other climbers, so you don't even need a space on your fence to plant this wonderful clematis, simply enough room to create a good planting hole.
Also known as texensis 'The Princess of Wales' and texensis 'Princes Diana'.
Awarded the RHS Award of Garden Merit

Cultivation Advice
The plants of the much sought after group of Texensis and Viorna have distinctive 'trumpet' or nodding urn-shaped flowers and are all excellent plants which deserve space in anyone's garden. Used as climbers, they all prefer a situation that is sunny yet not too windy or they can be allowed to scramble over and through other plants which enhances their natural beauty. These natural climbers are classed as semi-herbaceous, as during a very hard winter their growth will die back and they will re-shoot from below soil level. Consistent watering in summer, combined with good rich soil will ensure they perform at their best.

About Our Plants

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

Great selection of clematis. My plants arrived promptly and were well-packed and in good condition. Followed planting instructions, which were with plants. I hope they will grow well - early days, and our soil clayey with clunch underneath, but if they don't it will be my fault!

Bought 2 plants - delivered really quickly so thank you. Unfortunately however, one has died not long after being planted. We have had a deluge of rain this July so perhaps this contributed . The other one is growing thankfully.

Well established and in flower! Beautiful Clematis!


Looks healthy.
02 August 2022  | 

Even though the stem is thin, as with most Clematis, the plant looks healthy. Have planted it in a deep pot against a trellis and it‰Ûªs already put out a shoot after 2 weeks. All other Clematis from Thorncroft have been successful and admired especially on our village garden walk.


Healthy looking plant

I can't say much as only recently planted but looks healthy and being in well. In this dry weather, I keep it watered.


Superb quality clematis

Seems to be settling in well as I have only had it a short time. I only buy clematis from Thorncroft as their plants and service are excellent.
