Ipomoea Heavenly Blue Morning Glory is the early dependable Clarke strain with vivid true-blue flowers. Vines climb 8-12 feet and bloom from mid-August until frost, about 90 days from seed.
Soak seeds overnight or chip the coat to aid sprouting in 7-30 days when sown 1/4 inch deep. Start indoors 3-4 weeks before last frost or sow outside after frost when soil tops 70 degrees, spacing 8-12 inches in full sun.
