Piracicaba Broccoli Seeds 100


Certified Biodynamic and Organic A lovely green sprouting broccoli. Small, loose heads with large beads and lots of tender, sweet side shoots. When the initial head is harvested, then the sideshoots begin to shine, producing well over a long harvest season. The sweetest broccoli we’ve grown! Great for bunching for the market or eating straight off the plant. Best as a spring or fall crop, though it has been developed in California to form heads in summer heat. Recommended for people who demand deliciousness.
