When to plant Blue Fortune Agastache

Plant Blue Fortune Agastache 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 5 to 10 range, spring means March to May and fall means September or October. 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 7 in March.
