Grandpa Otts Morning Glory

This legendary heirloom morning glory originated in Bavaria and was brought to the US by John Ott. The very vigorous vines grow to 15' in length and the exceptionally large blooms are a deep purple with a red star.

20 seeds






Germination: 7-30 days, chipping seed coat or soaking seeds overnight aids in the germination.

Germination Temperature: Optimum soil temperatures 70-80ºF.

Seed Planting Depth: Sow 1/4” deep

Starting Indoors: Start indoors 3-4 weeks before the last frost. Provide 70-80ºF soil temperature. Using peat, cow, or paper pots can help with the stress of transplanting, they grow delicate roots and successful transplanting may be challenging. Transplant into the garden after the last frost. 

Sowing Outdoors: After the last frost, when soil is over 70 ºF. Sow a few seeds every 8-12".

Growth Habit: Climbing

Height: 15

Soil Needs: Average to fertile, well-drained

Approximate days to flower from seed: 90 plus days. Blooms toward the end of summer, the middle of August until frost.

Uses: Climbs trellises, fences, and poles

Care: Water seedlings regularly until established. Amend the soil with compost before transplanting. Mulching helps retain moisture. Over-fertilizing can result in low to no flowers.

Morning Glory Quite Aggressive

My shipping experience was excellent! Items came within a few days of ordering. I loved the blooms but I had to constantly prune the vine as it took over my vegetable garden! I ended up pulling it out of the garden. I recommend it if you want fast and vigorous coverage as a stand alone but not as a companion planting. Good for an arbor or trellis.
