Overview
Pollination is not needed to harvest the bud heads. Seed saving requires flowering plants and isolation from other Brassica oleracea forms.
Notes
Broccoli crosses with other cabbage forms of the same species.

gas, gastrointestinal discomfort from overfeeding
observe
Broccoli is safe for pigs in moderation and provides nutritional value. Flower buds, tender stems, and young leaves can be given as supplemental feed. Due to high fiber and sulfur content, overfeeding may cause gas. Woody stems and moldy parts should be avoided. No known toxic compounds in normal broccoli parts. If mold is suspected or gastrointestinal signs persist, consult a veterinarian.
