Mix colours, shapes, and textures together in your border, leaving everything to grow and get jumbled together and embellish the beds and borders with plenty of gravel, shells, and pebbles to give that nautical feel. All that’s left is to pick plants suited to the seaside.
Start with Echium vulgare (viper’s bugloss) which is a tall, self-seeding plant which makes it really low maintenance. The upright spikes of tiny purple flowers will add height to your borders in summer when positioned in a sunny but sheltered spot. The bees and other pollinators love it too.
