Plants with red flowers

Discover some of our favourite plants to grow for red flowers.

The colour of red flowers is caused by the presence of certain biological pigments in the petals, such as carotenoids, anthocyanins and betalains. 

Red-flowered plants, chosen wisely, can be the crowning glory of a planting scheme. Grow them alongside plum-coloured blooms for a sumptuous border or container display. Or combine with zingy oranges and cornflower blues for bolder effect.

Plus, hot borders wouldn't be complete without red blooms combined with spicy yellows and oranges.
