Such a lovely bright colour, aren't they. Do yours spread like mad?! I have about 100, even in the lawn . . . but that's fine :)

Yes they add a nice zing of colour early in the season. I can't say they have popped up in odd places yet, but that is probably because I have not had then as long as some of the other plants that take over if I let them. All part of the gardening fun!
