Ecology

A perennial sub-shrub, found in open, dry rocky limestone grassland (of which it is a conspicuous component where it occurs), generally on S-facing slopes; also limestone crags and cliff edges. It is found on more skeletal soils than H. nummularium, and hybrid plants (H. x sulphureum) may be found in intermediate habitats at sites where both species occur. Lowland.
