We love lettuce.... especially a crisp romaine. The fancier salad mixes turn up their noses at humble little romaine, telling her to go play with iceberg. But on a hot summer day, nothing is as refreshing as that crisp crunch. Romaine can take the heat, when those dainty salad mixes just wilt into lettuce mush.
Jericho has proven itself as a great summer lettuce with good heat resistance. It hasn't gotten bitter or shot up a flower stalk. Ideally, I'd plant patches of it once a month for continuous lettuce in quantities that we could manage eating. In reality, I have gotten 2 successions planted (one in April, one in late June from transplants) so that's pretty good. I harvest it as a young head and let it regrow. It also grows well in the cool spring or fall.
