Great Lakes Crisphead was a pleasant surprise in my raised bed garden this year. It germinated quickly last spring and formed nice, if small, heads. Excellent flavor too. I planted again this Fall and it's thriving. I'm gardening in NW AZ and our nighttime temps are in the low to mid 30's, highs in the 50's. Great for all cold weather crops.
