Flowers appear in late Spring from the previous year’s growth. Any pruning should be done immediately after flowering ceases. This will enable new growth to establish before the end of the growing period. Late pruning will result in very few flowers the next season.
Regular feeding during the growing season and summer months with a long term blood and bone and sulphate of potash mix (10:1) + foliar feeding using for example Powerfeed or a mix of Powerfeed and seaweed solution (3:1).
Very similar to C. alpina, with perhaps the very slightly paler green foliage and flower colour of creamy white seperating these two species.
