Size and Form
Autumn moor grass is a cool-season, clumping grass that grows about 18 inches tall. It forms tufts and can be used effectively as a ground cover.
Autumn moor grass will grow in full sun to moderate shade. Moist, well-drained soil is best, but this grass is drought tolerant once it is established. Tolerant of alkaline soils.
This is a cool season grass, so its most active growth occurs in spring and fall. It will be semi-evergreen in winter and can act as winter interest.
Since this grass remains semi-evergreen through winter, it should not be cut back until early spring, before new growth begins. At that time, it can be cut down to the ground if needed or simply trimmed to remove winter damage.
Disease, pests, and problems
No common serious problems.
Native geographic location and habitat
Native to Eastern and Northern Italy into Albania.
The green to yellow green leaves are very narrow (1/4 to 1/8 inch wide) and up to 12 inches long. Leaves are evergreen to semi-evergreen depending on climate.
Flowering occurs in late summer and early fall. The tiny, silvery-white flowers occur on 6 to 8 inch tall spikes that are held above the leaves. The flowers are wind pollinated.
The small fruit (caryopsis or grains) form along the spike that held the flowers.
