Template:Taxobox Molinia caerulea (purple moor-grass<ref name=BSBI07>Template:Cite web</ref>) is a species of flowering plant in the grass family Poaceae, native to Europe, west Asia, and north Africa. It grows in locations from the lowlands up to Template:Convert in the Alps. Like most grasses, it grows best in acid soils, ideally pH values of between 3.5 and 5, however, it can continue to live under more extreme conditions, sometimes to as low as 2. It is common on moist heathland, bogs and moorland throughout Britain. Introduced populations exist in northeastern and northwestern North America.<ref>Template:Citation</ref>
Molinia caerulea is an herbaceous perennial bunchgrass (tussock-forming), growing up to Template:Convert tall (taller when sheltered by gorse and heather), with many closely packed stems. The leaves are coarse, green, taper to a point, long, flat and sometimes slightly hairy on top.<ref>Grasses by C E Hubbard, 1978, published by Penguin books</ref> Due to the dense tussock it is very resistant to heath fires. Its ligule is a ring of hairs, as in heath grass (Danthonia decumbens). The long narrow purple spikelets are a major identification feature - the panicle is Template:Convert long.
It flowers between July and September, later than any other species.
M. caerulea is cultivated for its panicles of purple spikelets on yellow stems. In cultivation it grows to Template:Convert tall by Template:Convert broad.<ref name=RHSAZ>Template:Cite book</ref> Numerous cultivars have been selected, of which M. caerulea subsp. caerulea 'Variegata' has gained the Royal Horticultural Society's Award of Garden Merit.<ref>Template:Cite web</ref>
