Slo Bolt Loose Leaf

'Slobolt' is a premier heirloom, loose-leaf lettuce (introduced 1946) renowned for extreme heat tolerance and resisting bitterness, making it ideal for summer harvests. It produces large, 12-14 inch, compact clusters of ruffled, light green leaves. Ready in 45-55 days, it is perfect for cut-and-come-again harvesting.
