White is probably one of the best colours to add to a shady border as it really helps brighten it up. Not only that but is incredibly soothing to the eye - a winning combination! This combination will provide a long lasting display, which will start in the spring, and wont finish until well into the autumn.
Planting tips:Stake the taller plants in spring if you have a windy spot, and watch out for slugs and snails. All the plants will benefit from a generous layer of mulch in the autumn.
You will need a border measuring 2m x 1m in a semi-shaded spot.
