About Broccoli Waltham 29 Seeds

Waltham 29 broccoli (Brassica oleracea var. italica) is a cold-tolerant heirloom that produces large, tight blue-green central heads followed by plenty of side shoots. These broccoli seeds grow into sturdy, uniform plants bred for fall harvest and dependable yields even in cool weather. It's a proven home-garden variety that keeps giving long after the main head is cut.

Who it's for

Great for cool-season gardeners who want a reliable, high-yielding broccoli with a big main head plus weeks of side shoots.

How & when to plant

Start indoors 5–6 weeks before the last spring frost, or sow in midsummer for a fall crop. Plant seeds 1/4–1/2 inch deep and transplant 18 inches apart in full sun with fertile soil. Broccoli prefers cool weather (60–70°F) and grows well in USDA zones 3–9. Steady moisture produces the firmest heads.

Harvest

Main heads are ready in about 70–85 days. Cut the central head while the buds are still tight and green, before any yellow flowers appear; the plant will then produce smaller side shoots for weeks. Harvest in the cool morning for the crispest heads.

Benefits & uses

Steamed, roasted, stir-fried, or eaten raw, Waltham 29 offers sweet, tender florets and stalks for everyday meals. Its continued side-shoot production stretches the harvest well beyond the first cutting.
