A mixed selection of green and red varieties, Oak Leaf lettuce owes its name to the lobed, jagged shape of its leaves, resembling oak leaves, tender and delicately flavoured.
It belongs to the species Lactuca sativa var. crispa, family Asteraceae. A voluminous, compact plant, with spreading, lobed leaves in a mix of colours from bright green to intense red.
Sow in succession for most of the year, with a growing cycle of about 30-60 days, suited to both cut-and-come-again and whole head harvesting.
Easy to grow even in summer, it adapts well to organic cultivation thanks to its natural resistance to downy mildew and lettuce red aphid.
After cutting it regrows quickly: it is best to cut the head leaving 2-3 cm from the stem, to encourage fast regrowth of new leaves.
Thanks to its natural resistance to downy mildew and red aphid, it is easier to grow organically than other lettuce varieties.
The mix of green and red colours makes it particularly striking in mixed salads; the tender, sweet leaves work well both for cut-and-come-again and whole head harvests.
Rich in carotenoids, iron, potassium and vitamins A, B2 and C; the red leaves add an extra dose of antioxidant anthocyanins compared to the green variety alone.
