Which plants self-sow easily for you?

Baptisia
Salvia May Night
Penstemon Mystica
Centaurea Montana
Purple Coneflower

This year I have lots of seedlings from the new varieties of baptisias that
grow in the same bed! I am curious to see what they will look like. But I have to move them to another bed and then weed out all the rest so they won't infiltrate.

Impatiens balsamina
Cerinthe
Larkspur
KMOGG
Poppies (annual)
Honesty-variegated (lunaria annua)
Coreopsis tinctoria
Euphorbia marginata
Echinacea
Tinantia pringlei
Cymbalaria
Dill
Fennel
Cilantro

Oh yes, the herbs, etc. I am growing these in separate patches by the fence this year and hope to let them self sow forever!
Arugula
Kale
Lettuce
Morning Glory

Don't forget about columbines, forget-me-nots, dwarf fairy candytuft, shasta daisy, sundrops, snapdragons, and I'm sure I've forgot some.

Milk thistle
Some sunflowers

Milk Thistle??? That isn't a weed, is it? Of course, all weeds are vigorous self sowers!

It has medicinal uses. I think it's pretty - just don't walk through a patch of it.

Also:
Asters
Columbine
Oriental Poppy

I've always saved the seeds from the coneflowers, didn't know it would reseed. What about the BeeBalm? Same difference. You save the seed pods from it, does it reseed like the coneflower if you leave the pods on the plant?

A couple not mentioned yet that always reseed for me...Eriogonum grande var. rubescens. Anagallis monelli, Salvia canariensis, Erigeron karvinskianus, hollyhocks.

Oh, hollyhocks, they do reseed prolifically for me, too. I hadn't even heard of Eriogonum grande var. rubescens--that's a pretty attractive plant, think it'd reseed in zone 5?

I'm not sure if you could do it in zone 5...it's only hardy to zone 8, and I don't think any of my seedlings that have come up have bloomed in their first year. There might be other Eriogonum species that would do well in your area though and reseed for you.

Bah, most of the pink ones seem to be zone 8. I have zone envy ;)

Rudbeckia of course! Especially "Goldstrum"
My centaurea montana has self seeded a pink variation! Not quite as vigorous as the blue, but it still comes back every year. Purple coneflowers often produce variations.

French Marigolds
Poppies
Cilantro
Dill
Hopefully I'll have morning glories, cleome, and more self seeding in the future as well!

Wild Pointsetta, a red salvia, tall Mexican Ruella, and alstromera Parrot lily.

Just came across this great thread!

For me:
Rudbeckia
Gaillardia
Aquilegia
Echinacea
Monarda
Salvia
...and probably some I'm forgetting.

BTW...someone once told me that if you just crush the seed heads of Rudbeckia wherever you want more plants, the seeds are so "potent" that new plants will spring up without you having to do a thing.

For me

Wild Pointsetta
Red Salvia
Poke Weed
Confetti Lantana
Fushia and Yellow 4'0clocks

and of course Weeds, Weeds, Weeds! LOL

Oh, Yes...Weeds!

Caitlin... I have great luck with rudbekia... mine live in a half wine barrel and I just snap off the spent flowers...drop them back into the barrel and up they come every year....

I do the same thing with zinnias and poppies... all pretty flowers. Nancy

That gives me an idea. I could do the same with zinnias, etc. that will not self sow in zone 4, if I would have some planted in a container that I set in the garage over winter.

I don't know whether this is from seeds, but this year I have had Impatiens popping up in one of my beds. I live in Zone 5a. . .Impatiens die with the first frost!

Now, I'm not saying I have a bed full of Impatiens...and I can't swear it has never happened before...but I never planted any this year.

You can grow them from seed, why don't you try sprinkling the seed from this plant under the plant and marking it and see if it does it again next year.

Will I wipe out any self-sowing if I scratch compost into the soil after blooms fade?
Or add 1-2" of pine bark mulch mulch before spring?

Corey

Petunias and marigolds, Malva Zebrina. Has these been mentioned?

Definitely early sunrise coreopsis, salvia coccinea, purslane, commelina dianthifolia, and a few others.

I was afraid of that. It makes sense.

Doing things "at the right time" is tough when I don't have any habits or priorites established, and I've ALWAYS got twice as much to do as I have time.

I think this is "learning from mistakes" time.
Add compost in the spring and early summer.
Don't mulch where you want re-seeding to occur (or remove the mulch during seed-drop season and again during seed-sprout-season.

Corey

In agreement with the HH being almost weeds as far as self sowing, also my Malva and Coreopsis and of course the mint. AHH Aye Carumba.

Cut off the seeding stems and put them wherever you want, whenever you want.

Larkspur, poppies, and nigella, money plant, soapwort.

Anyone have any spare soapwort seeds? I have never grown them. Are they quite invasive? I think they would be a nice filler.

I had some soapwort where I used to live. I haven't grown them since I moved, but they did spread quite a bit. I never mind things that spread as I like to fill in spaces so weeds do not take over.

I'm cutting off some warm rosy pink Impatiens balsamina, I really like the white, cool pink, and spotty purple best. I don't want the hot color to reseed where it is, so I'll save some and toss some in the tropical garden where they'll look great with the warm colors.

I have lots of coco grass that continues to come up if anyone is interested in some.
