Description
Known for it’s well-wrapping leaves, ‘Twister’ self-blanches and reliably shields the snowy white heads from sun scald and rain discoloration. This variety consistently produces uniform, dense, medium-large heads and can withstand heat; in mild climates, it can even be grown year round! Mature cauliflower heads can be picked right away, but also hold well in the garden to extend the harvest.

Growing
Harvesting
Harvest heads in the morning, if possible and when buds are tight. Cut stalk below the head. Dunk heads in ice water to reduce any “field heat” and increase storage time. Allow to drain before storing.
Special Care
To ensure white rather than off-white or yellow heads, you can gently tie up the leaves or bend a few leaves, breaking the mid-rib and tuck them across the head for sun protection (blanching).
