OP, 65 days. This elegant heirloom has long, medium to dark green leaves that emerge from the central stem like ostrich plumes. It grows up to 1m (3) tall with blistered, strap-like leaves that are frost hardy, but tender when cooked. Lacinato is sometimes called Dinosaur Kale due to its large size and distinctive, prehistoric look. It is a descendant of Mediterranean kale.
