Hardy Green Winter Lettuce
For September Planting. Iceberg. This is next to Los Angeles Market as the heading variety for the Southwest for the summer planting. Of course it is better during the Winter months, but not so solid as the Los Angeles Market, which is strictly a winter variety, while the Iceberg is a good all season lettuce, and hundreds of carloads of Iceberg are being shipped when the other is not available. Iceberg Lettuce planted later than March 1st should be grown on dark, heavy soil, because if grown on light sandy soil, the heat of the sun reflected from the sand on the under side of the leaves causes them to burn almost to the heart. The light green, curled, red-tinged leaves of the Iceberg form heads as large as the Los Angeles Market, but not so solid, but it is as tender and crisp, and is of excellent flavor.
