Eriophorum angustifolium
Although "difficult to grow under cultivation", The Royal Horticultural Society states "Eriophorum angustifolium" can be cultivated as a low-maintenance wildflower, suitable for meadows, ponds margins or bog gardens. This may be done in sheltered or exposed terrain, but best accomplished with full sun at a south- or west-facing aspect, in water up to deep. Poorly-drained peat, sand, clay or loam with an acidic soil pH is required. Division in spring is the recommended form of propagation for the species, and regular deadheading is the recommended method of pruning. "Narthecium ossifragum" and "Myrica gale" are suitable for companion planting with "E. angustifolium". "Eriophorum angustifolium" is "generally pest free". As a seedling and young plant it is eaten by sheep and cattle, and a variety of goose species. It is tolerant to chalybeate (iron-enriched) water, but may succumb to powdery mildews.
