Most home-garden lettuce, especially the Bibb variety, goes to seed quickly when the temperature is high and the days are long. It quickly begins to form flowers and develops a bitter flavor in hot weather. This is called bolting. Buttercrunch, Salad Bowl, Ruby, and Romaine tolerate these adversities more than other varieties and remain sweet and tender longer.
