Erigeron acris syn. E. acer. Blue fleabane.
Life-form & Growth Form:
Therophyte/hemicryptophyte. Herbaceous annual, biennial or monocarpic perennial. Little/no vegetative spread.
Flowering period:
July and August.
Habitats:
Coastal sand dunes. Open, infertile, well-drained, neural to calcareous soils. Sand pits. Spoil, waste heaps from quarries, railway ballast, industrial waste and cylinders, rock outcrops of limestone or chalk.
Threats:
Primary threat is lack of suitable grazing to keep sward short and areas of bare, sandy turf which are needed for seed germination and seedling survival. As a result, plants are easily shaded out by tall herb and scrub communities.
