Overview
Iceberg is the heirloom crisphead that gave the whole type its name. Plants form compact, medium-large heads of firm, mild, crunchy leaves. It needs a cool season from start to finish: sow in early spring or late summer, since heat brings bolting and bitterness. Thin so each head has space, keep the soil consistently moist, and cut heads at the base once they feel full and firm, ideally in the cool of the morning.
