Brassica oleracea var oleracea Wild Cabbage RR DD N
This woody perennial looks just like cabbage with small greyish, glaucous leaves and can be found on the grassy slopes and rocks of the Great Orme. If you take the outer road around the great limestone rock, you can see the plant growing out of cracks and on ledges above your head but it also grows on the west sandy foreshore. It is possibly a native according to Stace.
It grows around much of the coast in England but there is not much to be found in Scotland or Ireland. Altogether there is enough of this plant recorded to make its rarity status a bit doubtful but the records most probably include escaped crop plants which are var. capitata etc. while the true wild cabbage var oleracea is uncommon.
