My lettuce and radishes are ready to eat.
When I first planted a small garden here, 4 years ago, I bought a mix salad seed packet from Jung's. Everything came in wonderfully, then they bolted. I kept the seeds of the ones that I really liked, separated and organized them. My favorite by far is Simpson, it comes up early and can be replanted through-out the year. Just as soon as I pull up one head, I plant another. So far this is the only one the will come into maturity successfully in high summer. I also have 2 types of Romain and buttercrunch, all are delicious, but have to eat them young in the high summer, though I can allow them to go to full maturity in the fall. Autumn is the time when I allow them to bolt and save their seeds for next spring. Lettuce is by far one of the easiest crops to grow. If you haven't yet,you can still plant a heat tolerant type of leafy green to get you a wonderfully fresh salad for the summer. They even do well in a pot on the window sill.
What kind of lettuce are you eating?
