Picking a border theme, for example by colour, is a great way to ensure it has a sense of cohesion. In this video clip, Monty Don plants Astrantia‘White Giant’, Cosmos‘Purity’ and bishop’s weed, Ammi majus – all of which have white flowers.
This beautiful salvia bears tall flower spikes throughout summer of deep blue-purple blooms, which are highly attractive to butterflies and bees. This delightful hardy perennial is ideal for the front of borders or in pots.
This RHS award-winning, repeat-flowering variety will brighten your patio from early summer into autumn with an abundance of snow-white, lace-cap blooms. Save £5 when you buy a pair of potted plants for £35.
