Creeping Bent

Creeping Bent - Agrostis stolonifera

Normally about 40 cm tall, but can be taller on rich soils. It has long creeping leafy runners that root at their joints, but no underground rhizomes. Panicles are pale whitish to purplish and rather closed up except when in flower.

Identification difficulty
ID checklist (your specimen should have all of these features)

The panicle is branched. Each spikelet contains only one floret usually completely enclosed by its glumes. The inflorescence branches close together after flowering, and have closely spaced spikelets which are not awned. The tiller ligule is longer than wide and pointed (i.e. on the non-flowering shoot).

Recording advice
