Erigeron glaucus (Sea Breeze)
This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.
Position: full sun
Soil: fertile, well-drained soil
Rate of growth: average
Flowering period: June to August
Hardiness: borderline hardy (may need protection in colder regions)
A low-growing, spreading perennial with blue-grey leaves and striking, lavender pink, semi-double, daisy like flowers with yellow discs at their centre. It will flower right through the summer and self-seeds into unlikely places such as walls and crevices.
This plant loves sun and sea air, and is a familiar sight around the coasts of southern Britain. Let it flow over a raised wall, creep through a rock garden or tuck it in the front of a border and let it run.
Garden care: Cut back to ground level in autumn and avoid winter wet.
