(40-70 days. Spinacia oleracea) A French Heirloom dating back to 1866. This huge spinach can grow up to 60cm (24″) in diameter, with 20cm (8″) crisp, dark green leaves. No matter how big it gets, the leaves stay tender and delicious with lower levels of oxalic acid than other varieties. Plants are ready for baby leaf harvest in just 21 days! A favorite spinach variety, extremely vigorous and particularly good for fall planting. You’ll get a small fall harvest, and the following spring it will emerge like magic before any pests are around.
