Why do mine change colour every year?

Last season, pink, season before purple, this year yellow.

I dug them up 3 years ago but up they come again. I gave up the fight and
let them grow where they want to. I like them............her indoors
don't.


Obviously coming up from seed and they won't come true from seed.
