Potato leaf

From Wikipedia, the free encyclopedia

Potato leaf, or PL, is one of two major styles of leaves which various tomato plants may have, the other kind simply being called "regular leaf", or RL. Each is broken down into a number of subcategories, but most basically potato leaf tomato plants have a smooth, pointy oval leaf, like the most standard sort of "leaf" one might imagine, while "regular" leaves have the normal tomato plant pattern of lobes serrating their edges.
