The most dramatic panicum flowers yet.

Panicum Bad Hair Day

Upright, yet weeping inflorescences sway in the wind.

Bad Hair Day provides multiple seasons of interest, from its upright growth habit to midsummer with pendulous grayish, yellow-green foliage; its dense and weeping inflorescences from late summer well into autumn; and its strongly upright stems again in winter that are an attractive light yellowish brown. Bad Hair Day is a large grass, so utilize it in the back of the perennial border as a backdrop for shorter plants. Grow individual specimen plants or mass it in larger landscapes. Effective for screening.

This is a large grass with an extensive root system, so space and site it accordingly. Adaptable to clay, loam, and sandy soils, as long as they are well-drained. We have not seen this selection lodge in our trials, but to be sure grow it in full sun with good air circulation, and avoid overly wet and nutrient-rich sites. With its genetic heritage, this selection may prove more salt and drought-tolerant than many selections of switchgrass (P. virgatum). Test it under these conditions and send us the results.

Please note: We don't sell plants. Asking your local retailer or googling the plant name is the easiest way to find someone selling our plants.
