Butter lettuce, also referred to as Bibb or Boston Lettuce, originates in the Mediterranean regions of Europe.

Appearance and Cultivation

Spinach has smooth, oval, or triangular dark green leaves that can vary from 1 to 12 inches in size depending on the age at the time of harvest. Butter Lettuce has smooth-sided leaves that can range in color from bright green to a deep reddish-purple hue.
