Anyone know what this plant is?

[LavenderfortheBees]

I found this growing last year next to my parking space in a tiny bit of scabby earth between a kerb and a fence. Must have self seeded and maybe some sort of weed? It had nice flowers so I moved it into the garden and it has tripled in size since last summer. Flowering beautifully but no clue what it is!

Can anyone help?

Antirrhinum. Snapdragons! They self seed here too. Gorgeous

Wonderful! I also get lots of aquilegia which self seeds and I leave because they are lovely and the bees like them. Same with bluebells which inexplicably includes a massive patch at the side (thankfully not the middle) of the lawn.

Mine are in full bloom too. The bees love them
