(30 days-baby, 56 days-mature. Heirloom) Vates Dwarf Blue Curled Scotch Kale. The lengthy original name of this standard kale is usually shortened to Vates or Blue Scotch. One of the most attractive of all vegetables in the garden, and can be grown as a spring or fall crop. The most commonly grown kale variety, it was introduced in 1950, out of the pre-1865 heirloom variety Dwarf Green Curled. Dense, frilly, finely-curled blue-green leaves on compact upright 12–16″ plants stand well, maintain color and resist yellowing in cold and heat. Hardy and productive. Good cooked or fresh in salads. Harvest all winter to zone 6. More variable than the hybrids.
