When to plant Purple Fountain Grass

Plant Purple Fountain Grass in early spring as soon as the soil is workable, or in early fall at least six weeks before your first frost, so roots establish in cool weather. For the middle of its hardy zones 9 to 11 range, spring means January to March and fall means October or November. Once settled, it blooms from July to October.

Month-by-month timing for your zone is on the planting calendar: for the middle of its range, start with zone 9 in January.
