Types of Tomato Leaves

There are 2 basic types of tomato leaves, potato (PL) and regular (RL). When you are planting different heirloom tomatoes it is important to make sure that the seeds you have gotten are what's advertised. In the few I am planting this year, the Brandywine Sudduth Strain is the only potato leaf. More information can be found on gardenweb about tomato leaves.
PLs are more rounded.
