Description More Information
This work saving variety will wrap and blanch itself as long as it's grown in cool conditions!

Pure white heads grow from 6 to 9 inches across. Average: 65 days

Detailed planting instructions:

Sow seeds indoors 4 to 6 weeks before average last spring frost. Keep soil warm (about 75 F), until germination. Then keep plants around 60 F. Provide direct sun so plants don't get leggy. When plants are 4 to 6 weeks old, transplant into garden 15 to 24 inches apart in rows 24 to 36 inches apart. Wait until soil temperature is 50 F or above and danger of frost is past before transplanting.

Larger, older transplants are more likely to bolt when exposed to cool temperatures in the garden. Transplant when plants have four or five true leaves.

Some cultivars will form small "button" heads when the weather turns warm following a 10-day stretch when high temperatures only reach the 40s F.

Direct seeding is more difficult than with other cole crops, especially in spring. For fall crops, plant seed in late-spring early summer ½ to ¾ inch deep, about 3 inches apart. Thin to final spacings. Or start transplants in late May and transplant in late June or early July.

Plants have shallow root systems. Avoid even shallow cultivation. Mulch to protect roots, reduce weed competition and conserve moisture.

To preserve the white color of the curd, use string or rubber bands to secure outside leaves over the head when it is about 2 to 3 inches in diameter. From tying to harvest may take less than a week in summer or as long as a month in fall.

Too much sun, heat or nitrogen fertilizer can cause "ricey" heads where the curd separates into small, rice-like grains.


When the curd flower head is 2 to 3" in diameter, pull three or four large leaves over the curd and fasten with a rubber band at the tips to shade and blanch the curd. Normal blanching time is 3 to 4 days, but may take longer in the fall.

Self-blanching types do not require this type of curd covering process.

Plants started in midsummer for a fall harvest will withstand light fall frosts and develop superior quality produce with a milder flavor than those that mature in hot weather. Light frosts will control insect pests allowing for fewer insect problems upon harvest.

Cauliflower should be harvested while the curd is still firm. When it is over-ripe, it becomes grainy or "ricey." When pulling off the curd, don't pull off all of the leaves - leave a row of leaves around the curd to prolong storage quality.


Cauliflower heads grown for seed should not be trimmed for consumption. If small amounts of seeds are wanted, allow individual pods to dry to a light brown color before picking and opening by hand. Lower pods dry first followed by those progressively higher on the plant. For larger amounts of seeds pull entire plant after a majority of pods have dried. Green pods rarely produce viable seeds even if allowed to dry after the plant is pulled.
