How To Plant Up A Damp, Shady Area Of The Garden

Follow our planting guide for colour along damp, shady river banks

One of the trickiest areas of a garden to plant up is a permanently damp, shady position; but there are solutions for those shady stream banks. It is much easier to choose plants which will thrive in any given situation than changing the growing conditions; which usually involves some sort of drainage works and landscaping.

There won’t be many flowers as they need sunshine to give a really good show and it’s no good planting spring bulbs which flower before the canopy closes over as they will just rot. These plants are recommended for permanently damp areas, not parts of the garden which are really waterlogged and boggy, for these areas you will need to plant pond marginal plants. You can achieve interest by choosing plants with differing leaf shapes and colours.

If you have an acid soil you can have a fantastic show of rhododendrons and camellias in spring. Flowering in late winter to early spring is Mahonia aquifolium which has lovely bright yellow flowers followed by dusky dark blue berries, which are loved by birds. Hellebores are always a welcome sight in spring and as they cross pollinate quite freely you easily increase your stock, and the most exciting thing is that you never know what the seedlings are going to look like.

Some plants self-seed quite prolifically which is always good news if you have quite a large patch to plant, but they can become a nuisance if you only have a small patch which is already crammed. There are several plants on the list which provide fantastic ground cover, which cuts down on the weeding and makes it less likely the prolific self-sowers can germinate.

There are some plants which flower in summer, but the amount of flowers the plant will produce depends upon the depth of shade; so don’t expect a profusion of flowers in this difficult area. If you have very deep shade try pruning out some of your tree branches or raising the canopy by taking out low branches. If this is not an option you can always add interest by including some statuary or creating a stumpery with old tree roots and then creating dryer planting pockets within the roots.
