Yes. In the high heat the lettuce will 'bolt' (put up a seed stalk) and turn
bitter. Moreover, the stalk will come right up through the center of the
head and possibly ruin it for other purposes.


This is a little late, but there's an argument for planting leaf
lettuce, since one can peel off the outside leaves for the table
repeatedly w/o having to pull up the plant.

Dunno if leaf lettuce would "bolt" as fast as iceberg, but it's for
sure much more nutritious; the darker the better.
