Clematis x triternata Rubromarginata

GardenAward

Masses of highly scented flowers produced throughout the summer

A deciduous late-flowering climber that is covered in masses of flowers which are marzipan-scented, purple star-shaped, edged in reddish-purple and borne on long stalks. The climber flowers very freely from midsummer to early autumn.

Where?

Happy in sun or part shade, in a spot where it can climb over a wall or fence or through a shrub or tree.

How?

Plant in moist, fertile, well-drained soil. Add goodness to the soil by digging in planting compost. Clematis like their roots kept cool so if they are not in the shade, cover the soil with slate or stone chippings. In the first year after planting prune back hard to approximately one foot above ground level leaving two or three healthy buds. On established plants prune back annually to approximately three feet in the winter or early spring before the plant starts to grow.

Clematis triternata Rubromarginata is an heirloom hybrid. It was first introduced in 1862 by Thomas Cripps. Pruning Group 3.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot at least 15cm away from the wall, fence or support. Dig compost into the base of the hole. Remove the pot and position the plant – along with its supporting cane in the hole, leaning onto the support. The top of the rootball needs to be 8cm below the level of the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Arrange and tie the stems onto the support. Water in well and keep well watered during the plant's first year. Mulch with bark chippings or stones to keep the roots cool.
