My tomatoes reseed. Love it.

As far as flowers - impatiens balsam, purple perilla, bachelor buttons, calendula, nigella, larkspur, rudbeckia and 4:00s just to name a few. It's a lot of fun and I love the jumbled effect.

Dill is the classic. I don't think anybody has ever planted dill twice. Watch out for horseradish! Tough to kill.

In the past 12 years, at 2 of my houses, only 1 flower has reseeded, and that was snapdragons. We had wood mulch at both of these houses so maybe that has something to do with it. But we bought snapdragons one year and they lasted another 3 years by reseeding. After that they "wore out".

But the following things we had and never reseeded: columbine, petunia, cosmos, morning glory, 4 o'clocks, pansies, foxglove, balloon flower.

Oh wait, we had Jacob's Ladder and, besides the main plant spreading, it grows easily by seed also. By the cooler temps at the end of August we would get the 2nd crop of Jacob's Ladder from seed growing up.

Romaine Lettuce Reseeds itself quite nicely! I had an earthbox ready to go for some green beans. My Romaine lettuce already had seeds on it and they were ready to fly. When I took them down I noticed a tiny plant in the earthbox. It was a romaine lettuce. I left it there and it took off! Everyother day I cut off two leaves for sandwiches and in two days two more are ready to cut. It grows fast! I have plenty of seeds if you need any let me know.

I am a lazy gardener, too, and although I now save seed in actual containers, I always seem to get the best results from the plants growing themselves. Nature knows best, right?

A plant tagged along with a raspberry bush from my in-laws 19 years ago. I let it live because it 'looked like something.' I got a yard full of black-eyed susans in just 5 years. I moved some to my next house, and eventually gave hundreds of volunteers away to family, friends, neighbors, and finally to total strangers.

One friend I gave some to said they didn't come back, so I gave her more the next year. Still didn't come back. Since they are vigorous volunteers, I was baffled and asked her a lot of questions. I knew she used mulch but even that doesn't usually stop black-eyed susans. Well, it turned out they were very neat gardeners and were cutting the plants off before they dropped seed. Duh!

For ChuckR and others who don't have that work for them, it is probably because they aren't lazy enough. :-) His wood mulch is probably too thick for plants to grow themselves much. Or people who 'tidy up' in their gardens and hence have no seeds to grow future generations.

Marcia, very lazy gardener

Does anyone know if Morning Glories reseed in Z5 MI? I know Chuckr30 said they don't in his garden, I was just wondering if anyone has had any luck.

Another GW member said they grow wild in OH. So, they do self seed in other areas, maybe it's too cold here in MI.

I'm prbably answering my own question. Well, if anyone has ever had a MG self seed in cooler zones.....let us know. Thanks. Great topic, I'm leaving a lot of plants to self seed too.

Hi Alice,
I am also in zone 5 and yes, my morning glories reseed. I have a white bed frame in the garden that I covered with chicken wire. Last year I planted MGs at the base of the frame. They climbed all over it and were beautiful. This year I didn't plant one and the frame is covered with the seeds that fell and reseeded. I like it, no work after the first year. Hope they reseed for you too.

I have the same 2 problems. I use thick layers of wood mulch to prevent weeds, but I think it also hampers reseeding flowers. Also, I get compulsive about deadheading (makes flowers look so much nicer!) so I don't give seeds enough time to mature. Now that's August is here, I'm trying to control myself with the deadheading!
