Waltham 29 Broccoli is a dependable heirloom variety prized for its cold tolerance, robust growth, and excellent flavor. Originally developed to thrive in cooler climates, this classic broccoli produces large dark green heads with thick tender stalks and dependable side shoots for extended harvests.
This variety is highly valued by home gardeners and market growers alike for its adaptability, productivity, and rich nutritional value. The dense heads are excellent for steaming, roasting, stir-fries, soups, casseroles, and fresh garden meals. Its mild slightly earthy flavor makes it one of the most versatile broccoli varieties for the kitchen.
Waltham 29 performs best in fertile well-drained soil with regular watering and cooler growing conditions. Light frost tolerance helps extend the growing season, making it an excellent choice for both spring and fall gardens.

How to Save Seeds
Broccoli will readily cross pollinate with other members of the Brassica oleracea family including cauliflower, cabbage, kale, and brussels sprouts, so separate varieties by at least 1 mile for maintaining seed purity.
Broccoli is a biennial plant and requires overwintering before producing seeds. Leave healthy plants in the garden over winter and protect them with mulch in colder climates if necessary.
During the second growing season the remaining heads will begin producing flower stalks followed by seed pods. Allow the pods to mature and dry naturally on the plant before harvesting.
Harvest seed pods once they begin drying but before they split open naturally. Finish drying indoors if needed, then separate the seeds from the pods and store them in a cool dry location inside labeled envelopes or airtight containers.

Great!
When looking for our seeds for this year, my husband and I wanted to prioritize a few things 1. Christian, 2. non-GMO/organic, 3. family owned 4. high quality. We were delighted to check every box with South Ga Seed Co. We were impressed with the variety of seeds, packaging, shipping time, and personalized note when our package arrived. We haven’t reaped the benefits of planting the seeds yet- but with the experience thus far we expect great yields!
