Lettuce Sioux


This medium sized summer heirloom iceberg looks very different from its basic, bland cousin! Its leaves are tinged in beautiful dark red, which only gets redder as the weather gets warmer. Delivering the crunch you’d expect from an iceberg,it’s an easy to grow variety that’s always a crowd pleaser.
