Cavolo Nero Overview

Brassica oleracea 'Bumpy-Leaf Kale' (Acephala Group) is most commonly known as Cavolo Nero, the Italian for Black Cabbage. Attractive and tall-growing kale that forms very dark green leaves with a bluish hue, that can be harvested repeatedly, all year round. Exceptionally rich in nutrients, it is a favourite choice of cooks because of its particular flavour and texture. It has been cultivated since the 1700’s and it is still widely grown in Italy. Also known as Black or Tuscan Kale, it can also be grown for ornamental purposes in a mixed border. If left to go to seed, yellow flowers are produced in Summer.

In particular from Cabbage Caterpillars of which several species of moth & butterflies feed on the brassica family. Commonly seen in autumn are the large cabbage white butterfly caterpillars that are yellow and black with obvious hairs on their bodies. Options for control are to remove by hand, spray with insecticides containing pyrethrum or biological control by using a product that helps with the bacterium control of moth larvae such as Dipel (Bacillus thuringiensis).
