Family in France grows there and I brought some seeds home, putting them in a Very Safe Place. Searching online I found Territorial had some a few yrs back, but Thompson and Morgan have something similar so I ordered and received some seed. These leaves look more "kaley", but we shall see. Someday I may find the Very Safe Place I put my other seeds.
You end up with a 4-6 foot tall stem with a cabbage head on the top. You pull the side leaves off as it grows to feed to rabbits or chickens (could probably eat yourself also) and it grows and grows and grows. They are very cool and I am excited.
http://www.thompson-morgan.com/seeds1/product/779/2.html(Jersey Cabbage) This famous Channel Islands heirloom kale makes a tall, straight stem, 2m (6ft) tall topped with a rosette of edible leaves. The stems when mature in the autumn can be cut, carved and varnished to make attractive walking sticks. Plants left in a second year may run to seed or increase in height to over 3m (9½ft).
