Traditional crop in Europe for generations. This type was grown by Thos. Jefferson in the early Nineteenth Century. In 1806, Bernard McMahon of Philadelphia said it was "the hardiest kind," and that may well be true to this day. Leaves are more pointed and arrow-shaped than the common type. The sturdy plants yield over a long season, producing flat, tender, medium-green leaves with red-tinged stalks. Slower to bolt than ordinary spinach. Traditionally sown in late-summer or early fall for harvest through autumn and into winter.
