Brassica oleracea (capitata group)

This 1969 AAS winner remains a champion in the home garden. Like the Toronto Maple Leafs who haven’t lifted the Stanley Cup since 1967, Stonehead still has throngs of devoted fans throughout the northlands, and it won our cooked texture and taste tests again in 2021. Early 4–6 lb round dense hard heads resist splitting—no need to rush out to harvest. That plus compact and healthy plant habit make it easy to grow. Not considered a storage variety, but keeps fine in the cooler. Tested negative for BR and BL.

Additional Information

Cabbage

  • About 150–350 seeds/g.
  • Days to maturity are from transplant date.

Blue-purple foods such as red cabbage and purple cauliflower contain anthocyanins and phenolics, which benefit the urinary tract, memory and immune system.

Culture: Exposure to hoarfrost is good for cabbages. They double their sugar content after one month of cold. Wire hoops and row cover should be used at early stages to keep out flea beetles and swede midge.

Red cabbage seedlings are often used for microgreens.

Minimum germination soil temperature 40°, optimal range 55–95°.

Brassicas

Days to maturity are from transplant date.

Culture: Start brassicas indoors March-May for setting out May-July, or direct-seed in May, or in June for fall crop. Minimum germination soil temperature 40°, optimal range 55–85°. Easier grown for the fall because many varieties perform poorly in hot summers. For better stands in dry conditions, sow in trenches and keep irrigated. Wire hoops and row cover should be used at early stages to keep out flea beetles and swede midge.

Note: because of a rule issued by Oregon, we cannot ship brassica packets larger than ½ oz. (14 grams) into the Willamette Valley, except those that have tested negative for Black Leg and Black Rot. Check descriptions for information.

Swede Midge—not as cute as it sounds!

Alert! Heading brassicas in the Northeast are seeing consistent damage from swede midge, a tiny gall midge. Its effects result in a non-heading plant. Wire hoops and row cover at early stages of heading brassica crops are becoming crucial for success. Some research also suggests garlic sprays as a possible organic repellent. Consult your Cooperative Extension resources for further information.
