Best plants for garden walls: 10 picks for garden boundaries (2024)

The best plants for garden walls will thrive when grown vertically up a garden boundary. These accommodating plants will spread over walls as long as there are gaps and crevices between the stones or bricks they can squeeze into or trellises and wires to scramble over.

Some garden wall plants don’t even need that, like ivy and Virginia creeper, which cling to surfaces naturally via aerial roots. Others love to cascade over the top, softening the hard lines of a wall and creating a lovely green screen.

When space is limited in small, urban spaces or balcony gardens, walls are an essential space saver to cram in more color and interest with plants. They are like a blank canvas (and a warm one at that) and lots of plants love to grow up and over them. Plants are also great for blending away unsightly surfaces.

So whether you want classic climbers like roses and honeysuckle or voguish succulents like sedum and sempervivum there's so much choice that we've rounded up the best plants for garden walls to make the choosing easy. Just make sure you remember to include plenty of evergreens so your retaining wall ideas don’t look bare in winter when everything dies back.

What can I plant in my garden wall?

You can either plant in the cracks and crevices of the wall or alternatively train plants to grow against the wall using a trellis.

To plant in the wall, choose young plants that will fit into smaller gaps and get established more easily than larger plants. Campanula, aubretia, sedum and thrift all work well for this type of planting. They will then creep over the wall and spread over edges into large and natural looking clumps.

To plant against the wall, make sure you have a sturdy trellis or ties in place to train the plants. Choose climbing roses, honeysuckle, clematis and vines for this style of garden wall planting.

Will clematis grow up a wall?

Clematis are one of the best plants for garden walls if you want to make the most of any vertical spaces in your garden. They will climb up trellises and walls with ease, quickly helping to disguise any less than beautiful features with a mass of flowers and foliage.

  • To help train your clematis to go up the wall, start by placing sticks in the ground directly behind the stem, at least 15in (40cm) away from the wall to help support the vines when they are young.
  • Once that is done, attach the vines loosely to the sticks with garden twine or plant clips. You want to allow the clematis some movement so that it can grow within the tie itself.
  • You will need to add sturdier climbing plant support ideas such as trellis, horizontal wires or netting as soon as your clematis gets going and begins to scramble up the wall to support it properly.
