Calluna vulgaris

While both are low-growing evergreen shrubs, Calluna vulgaris (heather) has overlapping, scale-like leaves, whereas Erica species (heaths) usually have needle-like leaves. Calluna vulgaris is also the sole member of its genus, while the Erica genus contains hundreds of distinct species. Additionally, Calluna typically blooms in late summer to autumn, while many Erica species bloom in winter or spring.

To keep common heather vigorous and compact, you should prune it immediately after it finishes flowering in the late autumn. Simply trim back the dead flower stalks and the top few inches of foliage, but avoid cutting into the old, bare wood. Regular pruning prevents the center of the shrub from becoming woody and dying out.

Calluna vulgaris absolutely requires highly acidic soil, ideally with a pH between 4.5 and 5.5, and excellent drainage. It naturally thrives on the nutrient-poor, acidic moorlands and heathlands of northwestern Europe. If planted in alkaline or clay-heavy garden soil, it will struggle to absorb nutrients and eventually die.

Yes, it is an ecologically dominant plant of European moorland and heathland habitats, playing a critical role for upland wildlife. It provides vital cover and nesting sites for ground-nesting birds like the red grouse. Its bell-shaped flowers also serve as a vital late-season nectar source for bees and butterflies.
