Sidalcea candida aka checker mallow

This plant is blooming now but I can't remember if we bought it or if it came in with some other plant. Didn't know what it was so had it IDed by some good soul on the Gardenweb 'Name that plant' forum as Sidalcea candida.

I initially looked it up using Google images but found only one site that had a picture of it and it was a French site so I thought this was a rare plant or one that was uninteresting to most gardeners. I did another search later and there are lots of photos - must have mis-spelled the plant nmae Sildacea ;)

Well it doesn't have really great flowers and the flowers it has are quite small so I don't know if I will keep it although it is a native so I'm in a quandry. I feel I should so maybe I'll just transplant it in a less prominent space in the yard. It grows in the wild mainly in the Western mountain states, Colorado, Wyoming, Utah, Nevada, New Mexico so how did it get here?
