Low-growing alpine plants, ideal for the small garden, rock garden or raised bed planted in 3s and 5s for the larger garden.
Most smother themselves in flower and have small scaly leaves and are dense twiggy growers.
In the north, grow in plenty of light away from drips from trees.
In warmer and more southern climates, they are best in part-day shade.
Bred by Peter and Kenneth Cox, the bird hybrids are grown all over the world.
