Blue Muhly Grass (Muhlenbergia lindheineri) - If you're a fan of ornamental grasses, Blue Muhly Grass seeds are a great addition to grow for the landscape. Sometimes called Lindheimer's Muhly, this Muhly ornamental grass has bluish gray foliage that grows in a clump 24 - 48 inches wide and 24 inches tall. The flowering spikes, appearing in fall, stand well above the arching foliage, up to 60 inches in height, and have an airy, billowing look that is beautiful and delicate.
Muhlenbergia lindheimeri seeds can be started outdoors, but be sure that you plant the ornamental grass seeds in an area where the plants will recieve at least six to eight hours of sunlight. Blue Muhly ornamental grass can tolerate partial shade, however, dense shade is not an option. Blue Muhly grass grows best in fertile, organic soil.
How To Grow Blue Muhly Grass From Ornamental Grass Seeds: In the spring, once temperatures are warm and frost danger has passed, prepare a seedbed by loosening the top 6 inches and raking to a fine tilth. Remove rocks and clumps and smooth the soil flat and even. Place Blue Muhly Grass seeds on the seedbed and press them firmly into the soil. Keep the ornamental grass seeds moist until germination occurs. Ornamental grass care includes cutting the plant back within twelve inches from the ground during the winter months before new growth in spring. After pruning, add a small amount of fertilizer to the soil around the ornamental grass.
