Waltham 29 is a time-tested heirloom variety believed to have been developed in Waltham, Massachusetts in the mid-20th century. It’s prized by gardeners for its dependable performance, especially in cooler weather and for fall harvests.
Produces a large central head, typically 4-6 inches (≈10-15 cm) in diameter, which is firm, tight, and blue-green in colour.
After cutting the main head, it continues supplying side shoots for weeks, giving extended harvests rather than a single cut.
Mild, slightly earthy flavour — great steamed, roasted, or raw. Keeps good texture and taste when frozen.
Days to harvest: about 75 days under favourable conditions.
Height / Plant Size: Plants reach about 50-60 cm (≈20-24 in) tall when mature.
Growing conditions: Thrives in cool seasons (spring or fall). Full sun is best, though it tolerates light shade. Needs fertile, well-draining soil and consistent moisture.
