Butterhead type lettuces are known for their 'buttery' taste and velvety texture, and small loosely formed heads. Relative to most other lettuce types, Butterheads are slightly more tolerant of heat. Even so, they are best planted early or late in the season in spring, away from the intense summer sun. They may be started indoors several weeks prior to the last frost of the season. Partial shade, or a location that receives primarily eastward exposure may be helpful if growing in summer. Butterheads usually need between 55-60 days to reach maturity, so plan your plantings accordingly. Leaves can be collected throughout the growing cycle. Space plants 10-12" apart with 12" between rows.
