Flowers that naturally spread

[Mamabear04]

Could anyone recommend flowers that naturally spread? Forget me nots? Any others?

Dandelions

🤣🤣🤣

Love in a mist, it gets everywhere!

My current big love - Erigeron! It’s decorating so many ugly places for me. It’s like a pound shop gypsophilia in a way, blowsy with discreet leaves. the daisies start white and then turn pink. You’ll never be without it but it’s easy to tweak out if it’s in the wrong place.

So many will if you give it a few years. Just looking out the window:

Persicaria
Rudbeckia
Physostegia
Aquilegia
Viola Labradorica
Alchemilla Mollis
Verbena Bonariensis
Primula Japonica
Lychnis Coronaria
Lysimachia Clethroides

Ooh yes Alchemilla Mollus, very beautiful

Mint and Lemon Verbena.

Flowers that self-seed in my garden, but not as prolific as forget-me-nots:

Aquilegia
Nigella (blew in from a neighbours green roof)
Yellow poppies

Other plants:

Hardy geraniums (not the Mediterranean kind) - perennials that get bigger every year
Blue knapweed (name sounds awful but lovely blue flowers like cornflower)

Verbena bonariensis as a PP mentioned - and the bees love it, and it has a long flowering season.
Borage is another one. Self seeds every year, lovely blue flowers, great for the bees, and the flowers are good for decorating drinks - it has a mild cucumber flavour.

Lily of the Valley.
Bluebells
Snowdrops
Daffodil
Crocus

Most flowers that come from a bulb.

Hardy geraniums
salvias
penstemon

all flower throughout summer

Dryas
Nepeta
Ajuga

Purple toadflax
Grape hyacinths
Aquilegia
Honesty
Valerian
Chamomile

Myosotis
Verbena bonariensis

LOVE erigeron. I also use it pretty much everywhere; it's so versatile, attractive and easy. I love seeing big explosions of it in random places because it's such a prolific self-seeder.

Other suggestions:
Muscari
Buddleia
Fritillaria
Bluebells (English please!)
Daffodils
Primroses

Sweet woodruff (galium odoratum) - Mark Lane was waxing lyrical about it on the BBC’s Chelsea coverage.

It is lovely, but in my experience it grows where it wants to, which is not necessarily where you choose. Beautiful but strong willed!

My garden has got lots of patches of Canterbury bells popping up all over the place so that would be a choice. I also like the way Welsh poppies put themselves about.

Unless you have several acres to fill, or are prepared to be vigilant about pulling it up when it wanders I would watch out for the Italian Arum. Lovely dramatic leaves, flowers and seed heads, but it colonises like crazy.

Don’t. One word. Don’t. It is very vigorous and makes very dense mats so nothing else , like spring bulbs can grow through.

That’s not been my experience, Viques, in the twenty-something years I’ve had it in the garden. It spreads moderately fast but, here, it’s shallow-rooted and easy to pull out.

There’s two commonly grown Erigeron, E karwinskiana which is a sort of over enthusiastic daisy, perennial and E glauca, a perennial with slightly fleshy leaves and large (about 3-4cm across) purple daisy flowers with yellow centres.

Although it will try to get out into a more favourable position, it will grow where nothing else will, in dry shade under trees, and in deep shade. It’s nowhere near so invasive as it’s cousin Sticky Willy or Goosegrass

Be aware that one person/places 'flower that spreads naturally' will be another's no-show or total thug!

If you've got a damper/shadier part then persicaria and astilbes.
