It’s all about getting the right soil, plant and positioning. Pick for aspect and you can’t go far wrong, because choice plants will be suited to your set up.
For instance, Scabiosa atropurpurea ‘Black Cat’ loves full sun and can really work as a striking addition to feature pots but won’t do well mixed with ericaceous plants because it prefers an alkaline soil.
Don’t forget to consider the exposure of your land too. Use dense hedges to keep delicate plants better protected or determine which out of your front of back garden is more sheltered so that tender plants can use the house as a wind break.
An idea is to plant up containers based on a preferred habit. Jasmine and clematis are two of my favourite climbers and their foliage effortlessly lends decoration to otherwise neglected corners.
Else, a large fixed planter is great long-term addition to your garden—look to something like Passiflora (passionflower) ‘Amethyst’, which loves climbing up garden walls, to use the features in your garden to your advantage.
