March 19, 2010: Still in Trial, needs about 2 more weeks before cutting the first heads.. but it's looking good (Pic). Container friendly, hardy to below 24 degrees and prolonged nights into freezing temps. No issues with disease.

April 16th, 2010 : Rock Solid 3-5 lb heads (grown in containers) Very sweet. This trial included the plant over-wintering. Holds on the plant well.

I have not grown this variety, information only.

Introduced to the US in 1889, this solid cabbage is red throughout and uniform in size. A small to medium core and good flavor.

98 days from transplant.

This an old time open pollinated cabbage that I have not grown since the early 50's. Not much demand for red cabbage in my neck of the woods. It is not mammoth but it is a pretty dark shade of red. Size and season are about the same as the Danish Ballhead (7 -8 lbs and 100 days).It is as easy to grow as any long season (fall cabbage).


This plant has been said to grow in the following regions:

Saint Simons Island, Georgia
Troy, Virginia
