plant profile: lettuce

Lactuca sativa
Asteraceae family 



VarietiesThere are hundreds of lettuce varieties but we'll only be using leaf lettuces - those that don't form heads. Leaf lettuce seeds can be purchased as a few pre-mixed varieties which are chosen to compliment each other.

CultureLettuce is a cool loving crop best grown between 60 and 65 degrees Fahrenheit, but can grow in temperatures as low as 40 degrees. For salad mix or baby-leaf size sow seeds in a 2-4 inch band with about 40 seeds per foot.  Cover lightly with soil and keep it moist.
