I'm not here to give you a gardening lesson — this is Livingetc, not Gardener's World, after all, but if there's one piece of advice I give anyone for making raised beds and planters look better (as someone with a pretty magical container-based courtyard myself), it's to make sure you've got some 'spillers' in the mix.
Spillers, if you're unfamiliar, refer to trailing plants — ones that don't just grow up in the air, but will creep down the edge of your beds, breaking the lines and softening the edges, while giving your planting scheme way more depth and intrigue. It's a game-changer, and any time I see raised beds or planters now where everything just sticks 'up', I can't help but feel they're missing something.
