Grandpa Ott morning glory is a gorgeous heirloom morning glory once on the edge of extinction. Plants display large rich velvety royal purple trumpet-shaped flowers. Each bloom is embedded with a bright rose star, and pink throats make the flowers glow.
The vigorous twining, heat loving vines quickly climb to 12 ft. tall. Train Grandpa Ott morning glory on posts, trellises, fences, or arbors.
Growing Grandpa Ott 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.
