Calendula, Johny-jump ups, pansy, Chamomile, borage, allysum, sweet william.

Perennials that self-seed. purple coneflower, shastas, rudbeckia, golden margarites, lupines and delphs.

I'm sure others can add to this list.

Happy Gardening,
Sierra

Other perennials besides the ones listed already that self seed in my garden...blue fescue, pinks, heliopsis (both regular and loraine sunshine), salvias, some lilies (the ones with bulbets), cranesbills, Jacob's Ladder and some yarrow (especially the pastel mixture).

Trees that self seed...elm and maple.

Shrubs that self seed...cotoneaster and spirea.

These are another few for your list you are making.

The perennial bachelor's button (Centaurea montana) will take over your garden if you let it. Along with: Globe Thistle (Echinopsis) and Sea Holly (Erignium planum).

Forget-me-nots and poppies, of course.

Malva moschata (Musk mallow)!!! (Even seeding in my lawn!!)

Dandelions. :-) (Just had to add that one.)

Columbines will pop up everywhere, but they're always welcome in my garden.

Achilliea erythropoda (a very small lady's mantle. I've never had the large one self-seed, but I may be cutting off the flowers before that happens.)

Clematis--especially alpina and integrifolia.

Veronica--not sure of the variety--maybe spicata. My neighbours across the street planted it--now, it's all over my garden, front and back yards. That's OK, because I love it.

Digtalis grandiflora (yellow, perennial foxglove).

Hmmmm. I'm sure there's more that others will add.

Doris

Some more annuals: Marigolds, Love-in-a-Mist (Nigella), Nicotiana (especially the large white ones), Morning Glories (some types more than others), Dill (not that it's a garden flower but the warning is warranted).

Perennials & shrubs: Columbine, Hollyhocks, Nanking Cherry

Welcome to the Far North forum, glad to have you here :0)

-Gillian

I've got a few to add that have self seeded this year for me in my Edm. garden.

Schizanthus
Helichrysum - straw flower
Gaillardia 'grandiflora'
Hesperis matronalis - Sweet Rocket, Dame's Rocket
Layia platyglossa - Tidy Tips
Portulaca - not alot but some

There's probably more, but I either can't remember or I pulled them as I saw them for control.

Welcome to FN, Laurie.

Just wanted to say hi and welcome to our Far North forum, hope you'll enjoy it here!

Sharon

Thank-you everyone. I will be much more careful in my planning & purchasing. Gone are the days when an annual was an annual & most perennials were too, lol.

Hi & Welcome to the Far North forum!

Here's a few more that I noticed in my garden:

Asters
Nemophila 'Baby Blue Eyes' - I'm assuming 'Penny Black' will too.
Sunflowers

I know you've had trouble with self-seeding, but the majority of those mentioned I would not actually go out of my way to avoid.

I avoid plants that are invasive via roots, but self-seeders I just pull out if I don't want them all. The only one that has ever really annoyed me is morning glories.

Just a thought.

Welcome..I dont think I can add any more to the list except for the lowly viola and pansy..savona

I have to agree wholeheartedly with Gil (northspruce) about leaving the self seeding. I pull where I don't want them, too. But this year, I have an area that is almost self-seeded and it looks really nice and natural with one type plant between another between another. I couldn't get those combinations that way, if I tried.

Shauna

It's not that I want to avoid self seeders completely but I've got some huge problems right now. The back 1/2 of the yard was previously vegetables. I planted it last year with a few perennials & lots of annuals to fill in, leaving pathways etc. If I wasn't constantly pulling, hoeing & spraying this year the entire area would have been over run & the plants I chose this year wouldn't have light to grow. & I am absolutely sure I didn't plant that snapdragon I just noticed blooming under the apple tree.
