Helianthemum ‘Fireball’ (Rock Rose), 1 litre pot

Rock Roses are versatile shrubby perennials, excellent for growing in the rock garden, or at the front of a hot, sunny border.

This selection has fluffy double scarlet-red flowers, over a mound of olive-green foliage.

Plants must have very good drainage, particularly through the winter. Trim plants lightly with hedge shears immediately after blooming, to prevent opening up in the middle. Evergreen in most areas.

Drought tolerant, once established, these will also put up with poor, sandy soils.
