Sometimes, lettuce will rapidly flower before it has produced its full potential of edible leaves. These include fused anthers that form a tube which surrounds a style and bipartite stigma. [1], The domestication of lettuce over the centuries has resulted in several changes through selective breeding: delayed bolting, larger seeds, larger leaves and heads, better taste and texture, a lower latex content, and different leaf shapes and colors. Different locations tended to prefer different types of lettuce, with butterhead prevailing in northern Europe and Great Britain, romaine in the Mediterranean and stem lettuce in China and Egypt.

He deals heavy close ranged damage to zombies both in front and behind him in a similar manner to Bonk Choy, he also has a chance to occasionally butter the zombies he attacks in a similar manner to Kernel-pult. Certain varieties contain more than others, and some selective breeding and genetic modification studies have focused on using this trait to identify and produce commercial varieties with increased pest resistance. It is in the sunflower family ( Asteraceae or Compositae – also known as the aster family, daisy family, or the composite family). This is particularly true for many of the looseleaf varieties, which wilt readily. You’ll need to snip the corners off of it so that it can have a mostly rounded top.
