Snow Mystique

Snow Mystique Cauliflower

(93 days) F-1 hybrid. On Oct. 11 our trialer noted, “I went out today and found two absolutely beautiful large heads of Snow Mystique. Big, tight and gorgeous!” Mystique has all the attributes we loved in Cassius: clean white dense well-proportioned heads, the same good upright habit and the dome shape to ward off excess moisture plus a tender flavor not expected from such a massive plant. Massive it was, heads rated at 1.8 lb average by our supplier, but double that weight in our trial. Perfect for end of September and early October when cauliflower is at its best in our climate. Can be slow-growing in higher elevations and cold spots. Tested negative for BR and BL.

Additional Information


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°.


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.
