How to Grow Candytuft
Iberis sempervirens
Candytuft (Iberis sempervirens) is a low-growing evergreen sub-shrub that smothers itself in pure white flower clusters from mid to late spring. It forms a dense mat 15-30 cm tall and is one of the finest plants for rock gardens, dry walls, path edging, and cascading over raised beds. Plant 30 cm apart in full sun and well-drained soil — it thrives in poor, stony, and alkaline conditions. Extremely drought-tolerant once established. The only regular care needed is a good shearing after flowering to keep it compact and prevent woody, bare centres.
Yearly Lifecycle
Care Essentials
No regular feeding needed. Candytuft prefers lean, well-drained soil. A light top-dressing of general-purpose fertiliser in early spring is sufficient if growth seems weak.
Watch For
- Clubroot in poorly drained soil (Iberis is in the brassica family)
- Slugs and snails on young growth in spring
- Leggy, open growth if planted in too much shade
Companions
Aubrieta, Creeping Phlox, Lavender, Dianthus

Shear after flowering
Cut candytuft back by one-third as soon as the flowers fade in late spring. This is the single most important maintenance task — it keeps the plant dense and compact, prevents woody bare patches in the centre, and often encourages a lighter second flush in autumn.
Full sun and sharp drainage
Candytuft is a Mediterranean sub-shrub that demands full sun and well-drained soil. It thrives in poor, stony, and alkaline conditions but will rot in heavy, waterlogged clay. If your soil is heavy, plant on a raised bed or add plenty of grit.
Perfect for rock gardens and edges
The low, spreading habit makes candytuft ideal for softening the edges of paths, walls, and raised beds. It cascades beautifully over stone and looks stunning paired with aubrieta, creeping phlox, and dianthus for a spring tapestry of colour.
Propagate from cuttings
Take semi-ripe cuttings in late summer after the post-flowering trim. Snip 8-10 cm non-flowering shoots, strip the lower leaves, and root in gritty compost. They root readily and can be planted out the following spring.
