In the garden
Erigeron glaucus originates from the west coast of the United States and sits in the Asteraceae family as a compact perennial reaching about 0.3 m. In the UK it comes into bloom from June to September, offering a reliable summer display at a low stature that fits the front of borders or tight rock-garden pockets. Plant it in full sun on a free-draining mix: it accepts sandy, loamy or clay soils provided they are well drained or only seasonally moist. Give priority to a sunny aspect and avoid permanently waterlogged ground; the species is fully hardy to H7, so it will withstand typical UK winters. For reference, its USDA hardiness is listed as zones 3–7. Use glaucous-leaved fleabane in coastal gardens, rock gardens and low borders where a compact perennial is needed. At roughly 0.3 m tall it forms a low element that complements taller perennials and bedding plants, and its glaucous leaves remain a season-long feature while the plant flowers from June to September.
