When to plant Sweet Autumn Clematis

For the middle of its hardy zones 4 to 9 range, spring means March to May and fall means August or September. Once settled, it blooms from August to October.
Month-by-month timing for your zone is on the planting calendar: for the middle of its range, start with zone 6 in March.
