There are so many herbaceous perennials it’s hard to know where to start. Although the main season is from late spring to late autumn, even through the winter months Bergenia and Heuchera have a good show of leaves. If you leave the dead stems on your herbaceous perennials until the spring they can look amazing covered in frost aswell as providing seed heads for the birds to feed on during the winter. There are herbaceous perennials for all aspects and soil types, even in semi-shade. Where there is a space between, shrubs or under trees make sure you plant some herbaceous perennials, they need little attention and will repay you by flowering year after year.
April is the perfect time to tidy up your beds and borders, remove any weeds particularly perennial ones and clear the old growth from your perennial plants. You will notice new growth appearing on your Herbaceous perennials so now is the time to put plant supports in place for the taller species i.e. Peonies, Heleniums, Campanulas etc. If plants are overcrowded or growing old and woody in the middle it’s a good time to dig them up, split them and replant young healthy sections.
