Yes — feather reed grass is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.
When does feather reed grass bloom?
feather reed grass typically blooms in early summer through late summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does feather reed grass need full sun?
feather reed grass does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is feather reed grass drought tolerant?
