A Whorl of Lettuce Leaves

My lettuce continues to grow.  I've planted several varieties.  This particular lettuce is not appealing to the bunnies, apparently, because it grows without protection and has not been nibbled to the roots.

Because of the unusual heat, several of my early plantings of lettuce have bolted.  I picked up a six-pack at Plant Depot earlier this week.  With the extremely high temps, I decided to hide it in the shade and plant once daily temps become more reasonable.
