Clematis cartmanii Avalanche
This mass of flowers belongs to a ferny-leaved, evergreen clematis, a scrambling non-clinging climber – or trailer – that can reach 2-3m. Preferring a sunny site, it has the largest flowers of any of the Cartmanii varieties and is happy in the border or in a container. It has gained a coveted Award of Garden Merit (AGM) from the RHS.
One for a sheltered spot in the garden, in well-drained soil, with the potential for some winter protection if temperatures plummet… No pruning necessary beyond a little tidy up after flowering, if that. Definitely no hard pruning, which will be quite resented!
