21 days for baby greens, 50 for mature leaves; both dates are from setting out transplants.Here it is, the cold-hardiest, most moisture-tolerant Kale we have ever grown! White Russian is, as its name suggests, a pale Siberian variety, and it brings tender-sweet flavor to either gourmet baby greens (ready in just 3 weeks from transplanting!) or full-sized leaves. You're going to rely on this super-gardenworthy variety!
