Danthonia decumbens (formerly Sieglingia decumbens) is a species of grass commonly known as the heath grass,[1] heath-grass,[2] or staggers grass[3] 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

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 Шаблон:Convert 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.[1]

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

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.[1]
