Check out Claytonia sibirica ( pink purslane )

Yes spot on, thsnk you! I grow Claytonia virginica. I wonder what evolutionary advantage the pinked petals give it?

Non native btw.

Claytonia siberica is also native to the PNW. Everything grows in Michigan it seems.

We have 20 native species of Claytonia and 17 of them are western. The genus was moved from Portulacaceae to Montiaceae.

This is yellow Claytonia virginica forma lutea, next to regular C. virginica.

This is Claytonia virginica var. hammondiae. Pure yellow with no stripes.
