  • Description

  • Notes

Bush muhly is a perennial grass with airy pink-purple seed heads that resemble cob webs in late summer to fall. It is drought tolerant but will need water every 3- 4 weeks once it's established, especially during the summer. This grass is not particular about soil type but prefers good drainage. It grows to a mature size of about 3' tall and 2' wide. This grass looks like a tangled group of leaves and stems, perfect for an organic look, wild garden.
Cold hardy to -25 degrees F.
