Lettuce Crisp Mint (Lactuca sativa) is a distinctive, high-performing heirloom romaine variety prized for its unique, deeply puckered foliage that closely resembles giant mint leaves. Producing upright, compact heads reaching 10 to 12 inches tall, it features rich, dark green, heavily savoyed outer leaves protecting a tender, pale green heart. Delivering an extraordinary combination of juicy crispness and sweet, refreshing, non-bitter flavor, Crisp Mint is exceptionally heat-tolerant and bolt-resistant, making it a standout favorite for summer Caesar salads, wraps, and continuous garden harvests.

Good to know

Superior heat tolerance and bolt resistance compared to standard romaine varieties, holding its sweet flavor well into summer
Unique puckered "mint-leaf" texture adds striking visual appeal and catches dressings exceptionally well in salads
Highly versatile—harvest outer leaves continuously as a "cut-and-come-again" green or allow to mature into full heads

Heavily textured, puckered leaves require thorough washing to remove garden soil or fine dust before serving
Dense upright heads require consistent watering to prevent interior tip burn during long dry spells
