Blackhawks Big Bluestem

Andropogon gerardii 'Blackhawks'

Plant Details:

Plant Type: Ornamental Grass
Plant Family: Poaceae
Plant Description: This upright native ornamental grass is a colorful accent plant for any landscape. It has slender leaves that begin dark green and turn purple when nights start to cool down. The foliage will be nearly black by mid-fall. Late summer brings beautiful purple-red, flowering stems that rise high above the foliage and are 3-pronged like turkey feet.

Maintenance:

Maintenance Type: Ornamental Grass - Medium
Plant Care: Ornamental Grass - Medium (showy non-turf grasses that go dormant in winter, 3-6' tall): Use hand pruners or hedger to cut and remove 2/3 of the total grass height. Trim edges. For warm season grasses (more common), this is best done in late winter to early spring. For cool season grasses apply the same maintenance practices in the late fall, once the plant is dormant.
