Go Back Grass Blackhawks Big Bluestem

Andropogon gerardii 'Blackhawks'
Deer Resistant IconRock Garden Icon

Plant Type: Grasses

Add drama to naturalized areas, urban landscapes, or even container plantings with this native selection of big bluestem. Blackhawks begins to show its dark side – in a good way – as early as August or when the nights begin to cool. The dark green foliage and nodes turn shades of purple as the burgundy inflorescences emerge and open to resemble turkey feet in mid to late summer. The color eventually intensifies to deep shades of rich purple that is nearly black by late September. Tolerant of a range of conditions, full sun will ensure the best color and habit. Excellent drought tolerance. A seedling of A. gerardii ‘Red October’, introduced by Intrinsic Perennial Gardens.
