A heritage variety forming a loose, decorative head of waffled, frilled leaves tinged with maroon. This cold-tolerant lettuce provides extended harvests into winter and beyond when picked repeatedly. Though excellent for autumn and winter growing, its ability to thrive in spring and summer makes this a versatile choice for seasonal salad mixes. 'Red Grenoble' is an ornamental and tasty cut-and-come-again lettuce, suited for gardens and containers alike, yielding tender, crunchy leaves with a delightful flavour.
