Lacinato Kale
Brassica oleracea var. sabellica
Dark, flat, blistered leaves with a deeper flavour and a tougher midrib than curly kale.

Flavour and texture differ from curly
Lacinato has a deeper, sweeter, less peppery flavour and a firmer leaf that holds up to long cooking - it is the kale for ribollita, braises and kale chips. The flat leaf is also far easier to wash than a curly one, where grit and aphids lodge in the frills.
Strip the midrib
The central rib is tough and stringy in mature leaves and should be stripped out for anything but long slow cooking. Fold the leaf and run a knife down either side, or pull the leaf off the rib by hand.
Harvest from the bottom up
Take the lowest mature leaves and always leave the growing point and at least six to eight upper leaves. Done consistently, one plant produces for eight months and develops a palm-tree form on a bare stem.
Frost makes it sweeter
Cold converts starch to sugar. Lacinato harvested after several frosts is markedly sweeter than the same plant in September, and it stands to around 10F. In zone 6b/7 it will often crop right through winter under a row cover.
Sowing and spacing
Direct sow or transplant. A spring sowing gives summer leaves, though they are tougher and more bitter in heat; a July sowing gives the best autumn and winter crop. Twelve to eighteen inches apart.
Soil and feeding
Rich soil, pH 6.0-7.5, and nitrogen side-dressings every four to six weeks to keep new leaves coming through a long harvest.
Pests
Cabbage worms and cabbage loopers - Bt or hand-picking; the flat leaves make caterpillars easy to spot. Aphids, especially grey cabbage aphid, cluster on growing tips in late summer and can be washed off. Harlequin bugs and flea beetles also occur. Row cover works well.
Storage
Keeps one to two weeks refrigerated in a bag, longer than most greens. It freezes well blanched, and the leaves also dry into chips at low oven heat.
