Clematis Cartmanii Early Sensation

Early on in the Spring Laura arrived with a beautiful Clematis with no label. We potted it on and popped it at the front of the house, which gets the early sun. It is now covered in beautiful white flowers and we have realised that it is Early Sensation. The Clematis variety Early Sensation is an evergreen clematis and can grow up to 9ft tall. It has finely divided leaves which emerge bronze when young and mature to a dark green. In spring this cultivar bears a profusion of scented, white, cup-shaped flowers each with a greenish-yellow centre. It belongs to the family Ranunculaceae. We are both excited and nervous. We love it but are afraid to lose it so lots of research needs to be done.

No routine pruning is necessary apparently. If the spread of the plant needs to be restricted prune immediately after flowering, cutting back overlong shoots to healthy buds. Apply a slow release balanced fertiliser and a mulch of well-rotted garden compost around the base of the plant in early spring. RHS

Clematis Cartmanii Early Sensation

Early Sensation and its cultivars originate from species native to New Zealand. It flowers prolifically and has attractive evergreen foliage which is non-clinging. This group of clematis is dioecious producing either male or female flowers. It is an early season clematis from pruning Group 1 so flowers early in the year on shoots produced in the previous summer.

This group of clematis is semi hardy and requires a warm sheltered position with a very free-draining soil in sun or partial shade. It is well suited to growing in pots using a well-drained gritty compost which can be brought into the protection of a cold glasshouse or conservatory in winter; it also makes a lovely subject for the alpine house. Plant your new clematis with the crown 2–3″ deep to encourage new shoots to grow from below ground level and keep it well watered during its first Spring and Summer. Clematis are greedy feeders and benefit from regular feeding.
