Which morning glories DON'T re-seed?
I've grown "heavenly blue" for 30 yrs and never had a problem with it re-seeding. Two yrs ago, I decided to grow Grandpa Ott on my veggie garden fence. Read...3 PLANTS! That rascal re-seeded at an alarming rate last year!! Terrified at the potential of them taking over my vegetable garden, I pulled every seedling I could find and don't believe a single plant produced seed. This year I had the same problem. Again, I've pulled 1000's of seedlings but they just keep coming. I even laid newspaper in some areas and mulched over it. It didn't stop em!
The only ones that don't get pulled are the ones that are hiding among my beans. Who says MG's won't flower in shade!! I have to go out every morning and search for the flowers so I can pull them. Such a shame too cause they ARE pretty. Now I'm terrified to grow any of the other beauties I see.
So which morning glories don't re-seed? I wouldn't mind if they re-seed a little but not to the point of becoming a chore....more like a "job" in the case of Grandpa Ott.
