DePurple Cauliflower

seeds
Brassica oleracea (botrytis group)
(68 days) F-1 hybrid. This colorful cauliflower makes no compromises: the stunning lavender-pink florets atop creamy stems keep their color when cooked and impart glamour and nutty sweet flavor to a sauté, stir-fry, fritter, soup—you name it! The distinctive color comes from anthocyanins, the antioxidants found in red wine, so DePurple is more nutritious than de whites. Uniform 7" domed heads on vigorous plants are wrapped tight in big leaves for good protection. Very slow to head up in cool weather, but does well in the late summer and fall. Tested negative for BR and BL. ⑥

We have decided to stop carrying varieties sold by Syngenta Group or its subsidiaries, Hollar and Goldsmith. Starting with the 2024 catalog, you will not see any Syngenta Group, or Code 6, varieties listed in our paper catalog. We will continue to sell some varieties online until our in house inventory is gone. Purchasing them will not further support Syngenta Group, but help us limit our losses and lessen the financial impact of our decision.

From early May through October 31, items shipping from our garden seeds warehouse ship twice a week, usually Tuesday and Thursday. For quickest turnaround time order online by noon Monday or Wednesday.

We will not be fulfilling seed orders from May 20 - May 22 while we do physical inventory count. Orders placed by Monday, May 19 at 10am will be shipped before the break. We will resume normal order fulfillment on Friday, May 23.

Additional Information

Cauliflower

  • About 100–300 seeds/g.
  • Days to maturity are from transplant date.

Culture: Cauliflower heads will “button” under stress. Do not allow seedlings to get pot-bound; avoid interruptions in growth. Most varieties can’t stand the heat and are not suitable for summer production. When heads first appear, bend leaves over curd to prevent discoloring. Wire hoops and row cover should be used at early stages to keep out flea beetles and swede midge.

Minimum germination temp 40°, optimal range 55–80°.

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.

Diseases:

  • BL: Blackleg
  • BR: Black Rot
  • BS: Bacterial Speck
  • DM: Downy Mildew
  • FW: Fusarium Wilt
  • FY: Fusarium Yellows
  • TB: Tipburn
  • WR: White Rust

Pest and Disease Remedies for all Brassicas

Major pests: Cabbage Looper, Diamondback Moth, Imported Cabbageworm
Cultural controls: control cabbage-family weeds near crop fields, till under crop debris of early-season brassicas after harvest.
Material controls: Spinosad, Bt.

Pest: Flea Beetle
Cultural controls: floating row covers, mulch with straw, time plantings for fall harvested crops only, crop rotation, perimeter trap cropping.
Material controls: AzaMax, Spinosad, PyGanic.

Pest: Cabbage Root Maggot
Cultural controls: time planting to avoid first hatching, use row covers, control weeds.

Major diseases: Black Rot, Alternaria Leaf Spot, Blackleg, Club Root, Downy Mildew, White Mold
Cultural controls: avoid transplanting plants with yellow leaves or v-shaped lesions, crop rotation, destroy crop debris after harvest, avoid overhead irrigation, control weeds, allow for good air movement.
Material controls: Copper.

Disease: Head Rot
Cultural controls: use well-domed varieties, harvest heads when tight, cut stalks at an angle.
Material control: Copper.

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.
