Summary

Andropogon gerardii 'Blackhawks' —commonly called Big Bluestem—is an extremely popular and beautiful cold-hardy variety of ornamental grass.

Often referenced as the "Monarch of the Prairie", this ornamental grass was once one of the primary components of the American tallgrass prairie.

Typically starting off in the spring as mixed shades of green, this grass often changes its color throughout the season, usually hitting shades of purple in the summer before transitioning into hues of black.

A great ornamental grass for many different locations. Plant groups of them together to create an attractive landscaping bed, use in corner beds, with other perennials, with fencing, or to create borders.

Flowers may be cut and dried for use in decorations and arrangements.

Care

Big Bluestem Grass Care

Andropogon gerardii 'Blackhawks' is extremely low maintenance and easy to care for.

Fertilizations will accelerate growth and keep your plant well fed. We suggest using our slow release fertilizer, or something similar.

Water regularly after planting and throughout its first year of establishment, or in periods of drought. Although this plant is considered drought tolerant, its ideal soil is moist, rich, and well draining.

It may be cut back it it becomes too large, or falls over. It's suggested to cut back this grass in late winter or early spring. Leave at least 2" of foliage when cutting back.

Big Bluestem does best when grown in full sun, although we've heard success stories from partially shaded areas.
