LETTUCE Great lakes (Heirloom)

Heirloom variety of Iceberg (crisphead) lettuce from 1941 noted for having a denser head than most varieties.
This vigorous lettuce forms large well-rounded solid heads tightly folded in cooler weather with a good crisp texture and flavour.

Heat and cold tolerant with a good disease and tip burn resistant.   
Slow to bolt making this an outstanding variety for the home garden, containers and hydroponics.
