Piptochaetium avenaceumAlso known as:
Stipa avenacea, Stipa virginica, Stipa barbata
Piptochaetium avenaceum is a graceful, clumping grass with dark black, narrowly pointed seeds. Growing 1' to 3 ' tall, with an airy, fountain-like form, blackseed speargrass makes quite a statement in a moss garden, or rock garden.
This grass is native to moist, rich, well-drained transitional situations, in part to light shade. It will perform at its best in areas where it has little competition from other faster growing grasses. Zones 5-9
Propagate from seed in early summer.
The common names are a reference to the uncommon, black color of the seeds.
