This is one of the greatest improvements in Simpson lettuce in the last 30 years. It has the same tasty leaves, light green in color, and delicate sweet flavor as Black Seeded Simpson. But now it gives you an extra 30 to 40 days to harvest due to the bolting resistant nature of this selection. Going away on vacation for two weeks? Don't worry about it. Simpson Elite will be waiting for you when you return, and it won't be bitter that you took a little break. 42 days.
