ColourChallenge Wednesday Yellow - Ground Flowers

I need help! My mom planted these, a few years ago... and I have no idea what they are.
Any idea @thekittygirl @artemisnorth @traciyork ?

I want to plant them in my garden, too, as a nod to her work. I thought it was perfect for The Color Challenge - Wednesday Yellow - Photo Challenge started by @kalemandra. #colorchallenge #photocontests
