Growing Margot Koster Clematis

Tough and reliable, her flowers look best in partial shade, especially midday shade, because too much sun tends to fade the colour a bit - this is more of an issue in the South. Happy on the coast. It will perform best with its roots in deep moist soil.

Did You Know?

Bred in Holland by Marinus Koster around 1890 from Clematis patens and C. viticella. It is sold as Monsieur Koster in France. 

Planting and Care Instructions

Clematis viticella Margot Koster - growing instructions:

  • Give it a deep, moist spot to bury its roots into.
  • The soil needs to be well drained (it won't tolerate water logging).
  • Needs a supporting structure to climb - as all growth is pruned back each year, the plant will never overwhelm trees or shrubs that it climbs through.
  • Final height of 4m makes it well suited to scrambling through small to medium trees and shrubs.
  • Pruning group 3 - cut down all stems each year in early spring (before new growth begins) to a set of buds 15-20cm above ground level.
  • All clematis like a mulch of well-rotted manure or garden compost in late spring.
