Lettuce – Oakleaf Green

Also known as “spinach lettuce”, Oakleaf Green is a beautiful, soft green, sometimes golden, lettuce that produces open rosettes with delicate, toothed, lobed leaves. It can be harvested as it grows, leaving the core in place, but it can also be left to grow and harvested when the heads are mature. Cold tolerant, this variety is also heat resistant.
