Plants native to my lawn: wood sorrel

What's that three-leaf weed in the lawn. Must be clover, you say? Hmmm, clover doesn't have purple flowers like that. Nope. That is oxalis. This variety, Oxalis debilis, has large trefoils and little purple blooms. I also found another variety that has smaller leaves and yellow flowers. Both are edible. They have a bit of a citrus flaver to them. The flowers are sometimes called sour flowers. If eaten in large quantities, oxalic acid can is toxic.
These seem to grow year-round and the flowers are a near-constant source of food for bees. Despite their reputation as a weed, these are low maintenance flowering plants that add a bit of color to the yard.

I've also seen another variety in the yard that is much smaller and has yellow flowers.
