What a beautiful Lettuce! Does anyone know how well it would do as a container plant on our apartment balcony here between Houston and Galveston? I know I could tempt the wife away from her old standard "Iceberg" from the "chain" grocer down the street if I could coax a few of these varieties to grow here.
