Plants for a south-facing border

Check out some of our favourite plants to grow in sunny, south-facing beds and borders.

There are many plants that'll enjoy growing in a sunny, south-facing border. These spots can really bake in the summer months, so you need to choose plants that can take the heat.

For many plants, a bright spot like this is essential to prevent them from becoming leggy. It'll also encourage more flowers for a longer period of time. 

To break up your borders and add some texture, try dotting in grasses like stipa, deschampsia and miscanthus. Take a look at these grass and flower combinations for more ideas.

If not grown in full sun, tall-growing sedums like Sedum spectabile and Sedum telephium can flop over. Plant them in a south-facing garden to prevent them from becoming leggy.


Chamomile is a pretty, aromatic plant. Both annual chamomile (Anthemis arvensis) and perennial chamomile (Chamaemelum nobile) are easy to grow, and thrive in full sun. 

Mediterranean herbs

Mediterranean herbs like thyme, sage and rosemary not only come in handy in the kitchen, but they'll also provide pretty, nectar-rich flowers for pollinators. For ground cover, try rosemary 'Prostratus'.


Ornamental alliums can be used to great effect dotted amongst borders. They're easy to grow and will attract a range of pollinating insects. The seedheads can also be left in place to provide winter interest. Discover more plants with attractive seedheads


Catmint (Nepeta) is a favourite with pollinating insects. Grow in a light, well-drained soil and cut back after the first blooms have finished to encourage a second flush. Here's how to use it in a nectar-rich container display.

Euphorbia characias

Many euphorbias can be grown in full sun. For the front of the border, try the low-growing Euphorbia myrsinites. For something more statuesque, Euphorbia characias subsp. wulfenii or Euphorbia x pasteurii.

Cotton lavender

Cotton lavender, Santolina chamaecyparissus, is a Mediterranean native, so is perfectly suited to the sunny conditions of a south-facing border. The aromatic foliage grows to form a neat mound, and in summer, yellow pom-pom shaped flowers appear.


Pittosporums like Pittosporum tenuifolium and Pittosporum tobira are valued for their evergreen foliage and powerfully scented blooms. Provide them with shelter from cold, drying winds.


Bold, architectural plants like agaves make great focal points in sunny borders. Some of the hardier species are Agave montana and Agave parryi. To ensure their hardiness, it's critical that they're kept as dry as possible over winter. Grow in a very free-draining soil, and consider lifting or covering in winter.


Helianthemums, or rock roses, are low-growing, evergreen shrubs. Lots of flower colours are available, and they look lovely allowed to tumble over a wall and soften border planting schemes.
