Herbaceous clematis have been around for many years and are becoming more popular every year. There are four groups:
Diversifolia, Heracleifolia, Integrifolia and Recta.
Tips for the herbaceous clematis.
The Heracleifolia Group require hard pruning each year but this is much better left until April when the weather has improved. Do NOT prune these hard in autumn or winter when tidying other herbaceous plants as the Heracleifolia Group over-winter better with the old growth left intact.
The non-clinging stems of the Diversifolia, integrifolia and Recta require support to hold them erect, however they look very attractive when allowed to scramble un-supported through other herbaceous plants and boarders.
'Praecox' is a unique plant that makes excellent ground cover and is a favourite of Monty Don in his garden Longmeadow. Beware it is very vigorous!
