No timeline data available yet for this variety.
Sow seed indoors 8 to 10 weeks before your last spring frost. Keep soil temperature at 60 to 70°F for germination. Barely cover seed, as light aids germination, then transplant to larger containers or cell packs when the first true leaves appear.
Transplant seedlings outdoors after the last frost has passed. Space plants 10 inches apart in partial shade with moderate moisture.
For direct seeding, wait until soil has warmed to at least 65°F. Sow seeds directly into the prepared bed in groups of 3 to 4 seeds, then thin to one plant per group when true leaves appear.
Cut stems for arrangements when half of the florets on a stem are open, which allows buds to continue opening in the vase and extends the life of your cut flowers.
