Know before you buy
Undaunted Muhly requires well-draining soil to thrive. It is particularly important that the soil does not stay soggy during the winter, as poor drainage can compromise the plant's survival.
This grass is a sun-lover and performs best in full sun exposure. Providing it with plenty of direct light ensures the most vibrant ruby-tinged flower spikes in late summer.
Yes, this variety is considered deer-resistant. While no plant is entirely deer-proof, it is rarely a target for browsing animals in most landscapes.
It is an extremely low-maintenance perennial. Simply cut the foliage back to the ground in late winter or very early spring before new growth emerges to keep the clump looking neat.
While it is primarily used in garden beds and borders, it can be grown in containers as long as the pot has excellent drainage. Keep in mind that container-grown plants may require more frequent watering than those planted directly in the ground.
For the best results, space your plants 18 to 24 inches apart. This allows enough room for the clumps to reach their mature size without overcrowding.
