When to plant Blue Crown Passionflower

For the middle of its hardy zones 6 to 9 range, spring means March to May and fall means September or October. Once settled, it blooms from July to September.
Month-by-month timing for your zone is on the planting calendar: for the middle of its range, start with zone 7 in March.
