Symphony

Symphony Cauliflower

(96 days) F-1 hybrid. Immense heads, up to a foot across, the classiest as well as the largest cauliflowers trialer Donna Dyrek ever grew, as tight as they were enormous, with no hollow stems. She raved about their sweetness and lack of brassica bite. Dyrek started the seeds on May 30, transplanted them on July 8 and harvested Symphony the 2nd week of October 2007. Requiring a long season, Symphony is for fall harvest only. Tested negative for BR and BL.

Additional Information

Cauliflower

Brassica oleracea (botrytis group)

~6,000–7,000 seeds/oz; 210–250 seeds/g.

Culture: Start like broccoli but needs more TLC. Do not allow to get pot-bound; avoid interruptions in growth. Cauliflower heads will “button” under stress. 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.

Minimum germination temp 40°, optimal range 55–80°, ideal temp 77°. Emergence takes 20 days at 50°, 10 days at 59°, 6 days at 68°, 63% normal seedlings at 77%, only 45% normal seedlings at 86°.

Brassica

Days to maturity are from direct seeding. Subtract 20 days from date of transplanting.

Note: We cannot ship packets greater than ½ oz. (14 grams) of any Brassica into the Willamette Valley. The State of Oregon prohibits shipping any commercial quantity of untreated Brassica, Raphanus or Sinapis because of a quarantine to control Blackleg.

Culture: Hardy. Require warm temperatures to germinate (68-86° ideal) but need 60s during seedling stage for optimal growth; higher temperatures make seedlings leggy. Heavy feeders; for best growth, need regular moisture and 2–3' spacing. Have done well for us succeeding onions and garlic in beds. Cauliflower and broccoli are damaged by hard frosts, especially in spring.

Young broccoli sproutlings make good microgreens.
