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, Heavenly Blue is rated 4.2 out of 5 by 34.
Rated 5 out of 5 by from Beautiful Blue Blooms Hold Up To Sun Never planted morning glory seeds before until this year (2019), but I am so glad I did! I planted Heavenly Blue and Scarlett Ohara on a fence at my deck. Heavenly Blue blooms hold up throughout the day, but Scarlett Ohara blooms collapse when the sun hits them. Easy to grow and what a joy to wake up to in the fall mornings.

Rated 5 out of 5 by from Beautiful I planted these late but they are finally blooming. They are beautiful! I did get a little worried because the bottom leaves fell off before blooming.

Rated 3 out of 5 by from Did not flower I let these grow in a planter at the bottom of a gutter chain. I got lots of lush foliage, but no flowers at all. I guess my soil was too high quality?

Rated 4 out of 5 by from Which I got more flowers, but loved the vines! I live in a city apartment and wanted to build a little urban escape on my balcony last year. I started these seeds outdoors in a 24 inch long window planter that hangs over the railing, next to the Burpees Giant White Moonflower.

Rated 1 out of 5 by from Poor growth I bought these along with the grandpa ott seeds, which grew like crazy but the heavenly blue barely grew. I planted some in pots and the rest into the ground and no luck either way. I've been growing morning glories for years so I soaked them and did my usual with no luck. I'm very disappointed since the blue is the actual color I wanted.

Rated 1 out of 5 by from huge vines, no blooms I have the same problem that nastyurchin had regarding the utter lack of blooms. I grew mine from seed and planted them in June. One is in full sun, another in morning sun, and another in afternoon sun. It doesn't seem to matter. The vines are so huge that I have to cut them back from taking over the space of other plants. Getting these plants started and thriving required a lot of attention, so I am disappointed in the results.

Rated 1 out of 5 by from So disappointed Last year, my Burpee morning glory vines grew and grew, and leafed, but never flowered. (I had been growing supermarket flowering morning glories successfully in our front window boxes for more than 25 years, but was splurging on seeds from Burpee.) This year, the morning glories and the moonflowers (I thought I'd try) never even sprouted. So I'm now done with Burpee.
