Plants for full sun will find happy homes in south and west-facing gardens. Sun-loving plants tend to be bright and vibrant florals who soak up rays and transform them into sensational colours and scents.
The right plant, right place principle in garden design helps avoid disappointment having plants fail on you. So buying plants specifically for their preferred conditions is a smart long-term investment.
"Some gardens, such as south-facing ones, are exposed to lots more sunlight and heat than others, so it is important to choose plants that will thrive in bright conditions," says Charlotte McGrattan, Hillier Garden Centres Head Nursery Stock Buyer.
Plants for full sun to choose for bright garden conditions
"There is a wider variety of plants for full sun than ones, which like shadier environments, so there is plenty of opportunity to incorporate fantastic colour, texture, and interest to your garden landscaping," says Charlotte McGrattan.

Also known as red-hot pokers, this perennial plant is a great choice for a warm and exotic border.
“Kniphofia flower throughout much of the year – from March to November – so are ideal for adding colour into gardens through all seasons but winter. Colours are wild and varied – from red and orange, through to yellow and green, and even brown and pink," says garden designer Melanie Hick.
"Growing up to 210cm, they are also ideal for adding some height and creating zones in gardens, or even as garden screening from neighbours," she says.
Melanie Hick will design a show garden at the prestigious RHS Hampton Court Flower Show 2024. The “Climate-Forward Garden” will embody the core principles of MHGD, depicting a front garden re-imagined for today’s ever-changing climate.

"Aptly named, sunflowers love the sun and need around 8 hours of direct sunlight per day ideally. In fact, the large flowers will turn to follow the sun throughout the day. As your sunflower begins to grow tall, I recommend tying it to a supporting cane with string,” says plant expert at Hedges Direct Jamie Shipley.

The trick to adding vibrant hues to the garden is Leptospermum scoparium, or ‘Red Damask’. A dense medium-sized shrub which will flower from late spring.

“Commonly known as switchgrass, this deciduous, perennial grass grows to 1.8m tall, ideal for adding ground coverage where needed. Not only that, but it adds some pretty colour too, with airy sprays of tiny, purple-green flowers produced from mid-summer to early autumn," says Melanie.
"The leaves turn a beautiful rich reddish-purple colour later in the year. Switchgrass is proof that low-maintenance garden plants can be both functional and beautiful. It originates from North America, where it is dominant in prairie land – ideal for a sustainable, climate-forward garden,” she says.
"Achilleas love a sunny position out in the open and enjoy well-drained soil. They come in a stunning variety of colours such as yellow, pink and orange. Their flat-topped flowerheads attract all sorts of pollinators including butterflies, bees and hoverflies. Making them good for eco-friendly gardens," says garden expert at MyJobQuote Fiona Jenkins.
"Achillea, such as Achillea millefolium at Crocus do well in cottage gardens, wildflower meadows and sunny borders and are quite simple to care for. Simply cut back any old foliage in the spring and deadhead regularly during the summer to encourage more flowers," says Fiona.

“Iris germanicas (bearded iris) are eye-catching flowers with their unique petal structure and shape and make a great feature bloom in a hot and sunny environment. These blooms are perfect for south-facing gardens as they thrive in a sunlit spot where the soil is a little drier,” says Charlotte McGrattan.
The thick root system of border irises stores water, so they need full sun and free-draining soil. Irises attract bees and butterflies with their vibrant flowers. Although irises like well-drained soil, they can grow in sandy or clay soils as long as the drainage is good. Their adaptability makes them great for all kinds of gardens," says Jane Dobbs, garden expert at Allan's Gardeners.
