What I learned about Japanese Morning Glories - year one.

Nashville, TN(Zone 6a)

This was my first year of growing JMGs. I decided to give them a try because regular morning glories - wild, grandpa ott and crimson rambler have nearly over run my place so this seemed like a good place to grow morning glories.

I have learned the following things:
1. JMGs don't set seed like common morning glories. You won't have as much seed.
2. The more variegated the leaf, the more tender the plant is.
3. Many morning glories are mislabeled -- even from major seed companies.
4. Where I live, the south side of the house is fine for grandpa ott/crimson ramble but too hot for JMGs.
5. JMGs are very sensitive to frost- even the ones that didn't die seemed to struggle to come back while the volunteer MGs just paused for a week or so and then took off.
6. Some of the plants have wonderful foliage and could be grown for the leaves alone.
7. They are beautiful and worth the extra work.

This spring will be my first year to grow jmg, Im excited. Thanks for the info. Are they heat and full sun tolerant? Thanks Rose

My impression is that they wouldn't mind a little shade during the late afternoon but otherwise, they are OK with sun. If they have heavy variegated leaves, they might like a little more shade.

Good observations... I find my outside Ipomoea nils tend to have the leaves burn and shrivel if they get hit by strong, direct sunlight. I think they like a little shade...especially during mid-day.

If you are growing for seeds, grow them in pots and bring them inside before the first frost. You will get LOTS of seeds that way....believe me! I have so many I don't know what to do with them all and the nils are STILL blooming and setting new seeds as I type.
