ERIGERON

Erigeron is usually associated with the herbaceous border, but there are a few dwarf species which belong in the rockery. These sun-loving plants are not difficult to grow, and their Daisy-like flowers add colour during the summer months.

VARIETIES: The most popular species is E. mucronatus (E. karvinskianus) – height 8 in., spread 2 ft.

Flowering period: June-September. The delicate appearance of this plant belies the robustness of its true nature. It can spread quite quickly by means of underground runners and may be too invasive for the small rockery. It flourishes in crevices between rocks, cracks between stones and crannies in walls. A colourful plant – the flowers darken from white to deep pink with age. In a severe winter the top growth may be killed, but new leaves will appear in spring. E. aureus is smaller – height 4 in., spread 9 in. with golden flowers in June and July.

SITE AND SOIL: Thrives best in light, well-drained soil in full sun.

PROPAGATION: Sow seeds or divide clumps in spring.
