Palm Tree Kale Brassica oleracea (Lacinato Kale Group)

Lacinato kale is a biennial cool-season vegetable that has been grown since the 18th century in Italy, especially in the Tuscany area where it is a traditional ingredient in two dishes. 

These plants will grow 2-3 feet tall and do best in full sun and any amended well-drained moist garden soil. They can be directly sown in the garden or purchased as seedlings and planted in either spring or fall. In the south, they can be grown all winter long as they tolerate frost and light freezes. Provide adequate nitrogen for best results. Get a soil test before planting and fertilize according to the results.

This kale has blue-green long narrow leaves with a bumpy or embossed appearance. They are more tender and sweeter than curly kale and don't require much cooking. Harvest leaves from the bottom up as they mature to encourage further leaf production. in late winter they will begin to bolt and produce a cluster of yellow flowers. This kale can be eaten raw or lightly cooked. 

Use lacinato kale in the edible garden or plant among the perennials for winter interest.

Insects, Diseases and Other Plant Problems:  Nematodes are a big problem in sandy soils. Diseases may include leaf spot, black rot, podery mildew and bacterial leaf blight. See pests of crucifers to the left.
