I planted these for the first time, many of them popped up and were very beautiful. We had very hot weather early in the season and so far no bolting.

Excellent lettuce with a great flavor - not bitter. Had a hot summer and they didn't bolt until about 100 days (I continuously picked leaves). Was able to densely seed and grow successfully. Once plants get about 4 inches, start thinning by pulling them out entirely where necessary. Either leave the others to grow large, or pick leaves continuously. Leaves do eventually turn bitter when bolting starts, but they turn a darker blue-green so it's easy to spot.
