I usually cut or buy flowers for our patio table, but this year I potted a few oxalis in small white containers. They love the shade, so I'm hoping they'll make it through the summer under our umbrella. Did you ever see one "go to sleep?" They are sensitive to light and react to it by closing. Check out this short video. They're such charming plants, and it's almost impossible for me to resist them at the nursery. Don't they remind you of butterfly wings?
