excellent starter

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.

Finally an enjoyable lettuce

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.

Great starters lettuce

The time I sowed some seeds, it was the first time I planted lettuce. A bit slow to germinate, but that is probably my fault because I live in the south. Once they sprouted, they grew very quickly even though my soil quality wasn't that good at the time. I made sure to grow them in shady areas, and the lettuce was very large and delicious. Definitely recommend this variety for a first time gardener. Make sure to grow it in part shade for best results
