Day 109 of 365 days in the community garden

Some of the lettuces we've let go to seed have purple flowers. I was quite surprised because I thought all lettuces had yellow flowers. These flowers pictured are still closed, and during the day they open up into pretty purple flowers.

"Lettuce is like conversation; it must be fresh and crisp, so sparkling that you scarcely notice the bitter in it." Charles Dudley Warner
