Red Ball Jets Summer Crisp Lettuce is a delicious Batavian type variety that features deep red delicately savoyed (ruffled) leaves that uniformly fold over loosely capped dense round heads. Leaves are brilliantly colored and have a tasty smooth texture and sweet buttery flavor. Resistant to downy mildew, tip burn and slow to bolt, this gourmet favor thrives in the heat of summer. An excellent choice for all growing regions. 65 days. Packet: approx. 250 seeds.
