Seed Sowing & Growing Notes
In mild areas, seed can be sown in pots in the fall, overwintered in a sheltered spot, and planted out in spring. Everywhere else, sow seed 10 to 12 weeks before last frost and transplant out right around last frost. Provide a strong trellis or support for vines to climb.
Harvesting/Vase Life
Harvest when there are at least 2 unopened flowers at the tip of a stem. It’s especially important to use flower food. Expect a vase life of 4 to 5 days.
