Waltham 29, an heirloom broccoli variety, is grown as a flower, or head, vegetable with solid medium-sized dark blue-green heads. Broccoli is considered a superfood for its nutrient rich content, having a high (top 20) Aggregate Nutrient Density Index score (ANDI), or micronutrient-per-calorie density.

This herbaceous annual, a member of the crucifer or brassica family, forms a compact, stocky plant with large crops of side shoots. It prefers full sun and organically rich, well-composted, consistently moist, well-drained loams but can survive dry spells. Open pollinated, it produces seed that will grow true to variety, ideal for seed saving.

A cool-season, winter-hardy vegetable, the toughest of the cool-season crops, one of the first to be planted in the garden, it can be direct sown into the garden as soon as the soil is workable in early spring, before the last frost date. But it can also be started indoors and transplanted, spring and fall. It needs cold temperatures to germinate and grow, withstanding heavy frost and temperatures below 28 degrees, and becomes even sweeter with a light frost.

If you plan to start your seeds indoors, be sure to check out our Bio Dome Seed Starter Kit. With the Bio Dome, you can control the temperature, light, and soil mix to ensure your seeds become strong for transplant.
