Introduced by Peter Henderson & Co. in 1875, this heirloom lettuce has remained the most popular loose leaf variety for good reason. This highly adaptable variety produces juicy crumpled light green leaves with tender blanched inner leaves. Black Seeded Simpson will withstand heat, drought, and light frost, which is why it has been a trusted heirloom for over a century. Classic for salads and wide leaves do great on top of burgers and sandwiches.
