100 days. [Introduced by German immigrants ~1840.]
In the early 1900s, Virginia gardeners used to sow seeds of this variety and use it as a source of cut greens while the heads were forming. Large, flat heads weigh 10-15 lbs and measure 7 x 14 in. Low-growing heads have a short core and excellent wrapper leaves. May grow poorly in hot weather, but revives quickly in cool, wet weather. Very good keeper. Pkt (2 g).
