Tronchuda – Brassica oleracea

Brassica oleracea includes cabbage, kale, broccoli, cauliflower and kohlrabi. These cultivated forms emphasise different plant structures: leaves, flowering shoots or thickened stems. The wild form has thick, waxy blue-green leaves and yellow four-petalled flowers. A seed assortment therefore needs a more precise designation than the species name alone. The catalogue average is 300 seeds per gram, a useful reference when comparing bulk quantities.
