Growing and Maintenance Tips:


Any pure green blades should be removed with the root section, to preserve the plant. This plant spreads by rhizomes. Prune late winter to early spring to make room for new growth.

"Some states have declared the Japanese blood grass a noxious weed. The species is especially virulent in the landscape. While the red form is technically not invasive, it can easily revert to the green form of the plant, which has been named one of the 10 most invasive weeds in the world."

Additional Notes about Japanese Blood Grass:


Warm Season Grasses: These grasses are much slower starting in the spring. They do not push new growth until temperatures warm in early to midsummer. They flower later in the summer or fall with most blooms remaining into the winter. Most warm season grasses tolerate heat, humidity and drought; some even thrive in these conditions.
