Volunteer flowers from the last season?

[coreopsis]

I was wondering-some flowers can be "planted" when the season is finished and they will come up next year(e.g.from the stuff chucked into compost bin or mother plant scattering the seeds) .Nature knows best-when the conditions are right seeds will sprout without me thinking"when is the right time..."
I just wanted to ask you which flowers(maybe veg and herbs too)you know about that will grow without you planting them.
Just inspected my flower border and saw some calendulas and snapdragons from last year and pansies from 2 years ago(they planted themselves).I know sunflowers,dill and tomatoes do it either.
So?Any onther volunteer experience?(Not asking about dandelions and dock)

Volunteer basil, parsley, fennel, lovage in the herby line.
Sweet rocket (hesperis matronalis) and candytuft along with pot marigolds and viola in the flower line - I just love 'em! Oh, and aquilegia!
And as for the veggies - once you let chard bright lights seed they seem to come up for years afterwards! My most persistent ones being the yellow stemmed.

nasturtiums & poached egg plants (liamathes?)

[Flummery]

Limnanthes. And nigella seeds like the blazes. I've had it coming up for about 8 years. I love it.
California poppies. After a couple of years of deliberate planting you'll get continuous supplies of evening primrose, honesty and foxgloves too, as they're biennials.

Our entire garden is covered in poppies - they are even in hanging baskets!

Potatoes! tons of 'em all through my beans

In my experience; anything you don't want to come up, will. With a vengeance. Anything you're desperate for, won't come up at all, or if it does, it'll be in the wrong place!

Chrysanthemum Tricolor - yippee!

It's the sod's law of the gardening sometimes Glutton-the more you care,the less chance you'll get rewarded with a good harvest.
It depends on what is coming out of the ground-now I'm fighting with dock(very unwanted)but flowerwise-I have some calendula volunteers(nice to have)growing in the clump-I'm going to split them probably next week and plant them elsewhere.

[Lovage]

I think this is an interesting way to garden.
On my plot I have self seeding poppies, antirhinums, amaranthus, calendula, nigela and sometimes sunflowers,all used as cut flowers plus borage, limnanthes nasturtiums and caper spurge just to brighten odd corners. Sometimes I move seedlings to where I want them, sometimes I leave them where they pop up - red amaranthus in a bed of blue-green leeks was stunning. None of these are a problem to hoe up if in the way

As for veg, I haven't bought seed of rocket, land cress or lambs lettuce for about 7 years. I just let a few plants flower now ( look great and good for bees ) they produce seed most of which won't germinate til Sept when it's very easy to move them to a bed for salads all winter. Also works sometimes with red mustard and have just added re Orach and have a host of seedlings now.
Other veg self seeding include coriander, chard and leeks. The leeks make a wonderful display with the flowers but the seedlings seemed to grow too late to make much of a plant - I suppose I will have to collect them and store in spring
