Description

RubyBor Hybrid Kale F1 is a 2026 All-America Selections Gold Medal Winner prized for its strikingly deep purple foliage — a color unmatched by other purple kales, with dark blue-green leaves, bright purple petioles and ribs that hold their color even through summer heat. Highly uniform and beautifully curled, the textured leaves make a handsome bunch at market or in the garden. Tender and mild-flavored, RubyBor is ideal for edible landscapes, containers, and raised beds, with continuous harvest from spring until frost.

Growing Information

RubyBor F1 Hybrid Kale can be direct-seeded or transplanted, though we recommend transplanting for the strongest start and most uniform spacing. Start transplants 3–4 weeks before your desired planting date. This award-winning hybrid forms compact, bushy plants with striking deep purple foliage that holds its color throughout the season. RubyBor performs exceptionally well in garden beds, raised beds, and containers, offering both ornamental beauty and delicious harvests. Tender, non-bitter leaves can be harvested continuously from spring through frost.
