PLACEMENT & CULTIVATION
Grandpa Ott's' morning glory is a charming, old-fashioned twining vine with smaller flowers than the large saucers of I. tricolor–it's exuberant and abundant blooming more than compensates. Provide a tall trellis or fence for it to twine about. The blooming period begins in mid-summer and extends until the arrival of fall frost, the flowers staying open all day in cloudy weather or in the fainter light of fall. Self-sows, sometimes abundantly. Caution: seeds contain some toxic alkaloids.
Final Spacing:
1'
Water Requirements:
Medium Water Use
Watering Details:
About 1" per week, more during especially dry, hot spells. Drought tolerant when fully established.

Slightly acidic to slightly alkaline.
Fertilizer:
Mix in 2" of compost prior to planting and apply a flower fertilizer at bud set for more abundant blooming. Avoid nitrogen fertilizers that favor foliage growth over flower development.
