Morning Glory, Grandpa Ott

Short Description

Classic morning glory. Covers itself with flowers.

Full Description

Along with Heavenly Blue, this is the classic morning glory! Vines are extremely vigorous, up to 15 ft., and are literally covered with small, dark purple-blue flowers up to 3" across, with a red star at the throat. Thought to be originally from Bavaria, this is probably the easiest morning glory you can grow, and it will self sow even in cold climates.

Sowing Directly in the Garden:

  • Morning glory seed has a hard seed coat. To aid germination, nick or cut the seed coat with a nail file and soak the seed overnight.
  • Direct sow seeds in average soil in full sun two weeks after danger of frost has passed. Morning glory is a vigorous vine; choose a location next to a support for the vines to climb.
  • Morning glory is not generally recommended for containers.
  • Prepare the soil by removing weeds and working organic matter into the top 6-8 inches of soil; then level and smooth. Morning glory tends to prefer poor soils rather than highly enriched soil.
  • Sow seeds thinly and cover with 1/2 inch of soil.
  • Firm soil lightly and keep evenly moist.
  • Seedlings will emerge in 7-21 days.
  • Keep soil evenly moist but not wet.
  • Thin plants to stand 10 inches apart when plants are 1 to 2 inches high.
  • Do not fertilize unless the plants are showing a nutrient deficiently. Over fertilizing may produce lush green vines with few flowers.
  • Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
  • Remove plants after they are killed by heavy frost in fall to avoid disease issues the following year.
  • Morning Glory vines need little care and are easy to grow.
  • Plants can self-sow so allow some to set seeds at the end of the season if you would like it to come back next year. If you would like to prevent self-sowing, remove seed pods before the seeds are released.

Morning Glory, Grandpa Ott is rated 5.0 out of 5 by 7.
Rated 5 out of 5 by from Lovely plant I bought a packet of these a little over a month ago , i planted them in seed cells , then transplanted them out to my yard in Central florida , surprisingly despite the sandy , poor soil , they popped out flowers at 3 and a half weeks old ! they are about a week into flowering and the blossoms are about 3-5 inches across , the color doesnt really vary , which i like , and they bloomed the color i was expecting them to , if i had to , i would by them every year ! But since they are such prolific self sowers , i wont have to , since they'll plant themselves , and i will enjoy these for years to come , thank you Burpee !

Rated 5 out of 5 by from Completely neglected Threw a few seeds in the ground against a deck trellis in April. Sprinkled some granular slow release flower fertilizer at the start of the season then sporadically watered when I remembered (I was too busy tending to the veggies). Although a slow start, almost every seed germinated and the vines exploded once the weather warmed up; before I knew it the morning glories are wrapping around the handrail of the deck staircase. Major slug problem at the start of a wet spring but they didn't bother these. Colors are a standout. The vines nearest the house are in super sandy soil and get much less light but are slowly making headway with zero maintenance. I can only imagine what they would do if I had given them the time of day. Will definitely be planting again next year

Rated 5 out of 5 by from Beautiful & Amazing !! These are PERFECT!! And the color is vibrant. I tried morning glories in the past and they DID NOT make it. This time these are just beautiful. They have had a pretty quick start and grow, grow, grow. I'm SO HAPPY with these this year and are enjoying them so much!! Look forward to ordering them year after year from now on. Thanks Burpee for providing excellent seeds.

Rated 5 out of 5 by from Beautiful deep purple flowers I love this morning glory. Thinking I'd get a head start on the growing season, I sowed them indoors, but they didn't take well to transplanting. So, because the weather was warm enough, I direct sowed some seeds, and boy, did they take off! The color is beautiful -- a dark purple, just like in the photos, with a slight magenta tinge to the interior. They're really quite lovely. No real maintenance, either, other than making sure that they're watered during hot, dry spells.
