Solstice Broccoli Seed Organic

Regular price $2.95 $2.00 Sale

Our Solstice Broccoli seed is certified organic and open pollinated. (71 days) Open-pollinated. Has rapidly gained a following. Its tall leggy plants gave it its alias Oregon Long Neck. A grower harvested her first trial head right on the summer solstice from an April 11 start. Its mild sweet heads, at 4–5" across, are intermediate between Piracicaba’s and those of the domed hybrids.

Among the half dozen open-pollinated broccolis in our trial, Solstice was the most uniform and the sweetest, smaller in the summer and tastier in the fall even though turning purple in frost. Noted for its zillion side shoots that follow the main head. Best as a fall crop. Not adapted for summer crops in Zones 5 and south as heat causes irregular heads and side shoots. OSSI pledged.

100 seed per pack.  84% Germination 

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.

Broccoli 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 sprouts make good microgreens but these are not USDA approved for sprouts.
