Danthonia decumbens (formerly Sieglingia decumbens) is a species of grass commonly known as the heath grass,[2] heath-grass,[3] or staggers grass[4] It is a tussock grass native to Europe and adjacent parts of Asia and North Africa. It may also be native to Newfoundland and Nova Scotia.

Description

[edit]

Danthonia decumbens is a perennial plant with a decumbent habit; it lies on the ground with the tips turned upward.

It has narrow, bright green leaves taper to a sharp point and are rather hairy. A long upper leaf sheath clasps the delicate stem. The stem is 15–30 centimetres (5.9–11.8 in) high and slightly bent at the base, smooth with 1 to 3 nodes.

The ligule consists of a ring of hairs, as in the purple moor grass, Molinia caerulea, except that in this plant each end has a tuft of longer hairs.[2]

The panicle consists of 4 or 5 large erect glaucous silvery green or purplish awnless spikelets. These are arranged alternately on the upper part of the stem. The bunchgrass flowers in the summer months.

Ecology

[edit]

The plant is found on acid pastures and heathland, on sandy or peat soils, which are also often damp.

The grass, having no domestic forage value, is not grown agriculturally.[2]
