The most loved of all morning glories, Heavenly Blue features sky-blue flowers with white throats. Blooms are produced with great freedom on fast-growing, 12 ft. tall vines. Heavenly Blue was an instant success when introduced in 1931, and remains the most popular morning glory to this day.
Growing Heavenly Blue Morning Glory Seeds
Sow Morning Glory: Nick the pointed end of the morning glory seed with a nail clipper or knife. After nicking, seeds can optionally be soaked in water up to 12 hours. Then, sow in 2 in. pots or cell packs, cover with ¼ in. of soil. Kept at 70°F., seeds germinate in 7-21 days. Morning glory seed can be direct sown after all danger of frost, 6-8 seeds per foot. Thin seedlings to 12 in. apart.
Grow Morning Glory: Grow in full sun. Morning glory vines need good drainage, tolerate drought and poor soil. Blooming is heavier and growth is faster with regular water. Avoid overwatering and nitrogen-rich soils which produce more leaves and few flowers. Rarely bothered by pests or disease. Flowers from midsummer until frost. Hummingbirds love trumpet-shaped morning glory flowers.
