Agrostis perennans (Walter) Tuck.
Agrostis perennans is a grass.
Agrostis perennans was already described and the name validly published by Thomas Walter. It was Edward Tuckerman, however, who reclassified it into todays valid botanical systematics in 1843.
The comparatively short-lived grasses have a decumbent habit and reach heights of 30 to 100 centimetres. The main growing season is from spring to fall.
Agrostis perennans is deciduous. The dark-green, simple leaves are alternate. They are linear with entire margins and parallel venation. The foliage is porous.
Flowers and Fruits
Agrostis perennans produces green flowers from July to August.
The grasses produce only few brown caryopses from summer to autumn.
The plants produce rhizomes which give rise to vegetative spread.
The grasses prefer a sunny situation on moderately moist soil. They prefer loamy or clay soil with a pH between 5,5 and 7,5. The plants need a soil depth of at least 20 centimetres for good growth. They tolerate temperatures down to -35Â°C (USDA zone 4) and need a frost-free period of at least 17 weeks.
