Waltham 29 Broccoli is a top-notch variety suited for cooler climates, yielding medium-sized heads and abundant side shoots. Its non-uniform maturity ensures an extended harvest window, making it an excellent choice for home vegetable gardens. This broccoli is both easy to cultivate and delicious, taking approximately 85 days to mature.

Named after Waltham, MA, where it was developed by researchers at the University of Massachusetts in 1950, Waltham 29 broccoli traces its origins back to the wild plants found in the Mediterranean region and Asia Minor. Initially introduced to Europe and later to the New World, where it gained popularity in Thomas Jefferson's experimental garden, broccoli eventually earned the nickname "Italian asparagus" due to its appreciation in Italy. Following World War I, Sicilian brothers Stefano and Andrea D'Arrigo brought their broccoli variety to San Jose, California, before shipping it to Boston's North End, where it found a thriving market.

Waltham 29 Broccoli boasts blue-green heads ranging from 10-20 centimeters in diameter, with long stalks and medium to large beads. This variety excels in cooler weather conditions, making it an ideal choice for autumn cultivation. Its exceptional taste remains consistent whether enjoyed fresh or frozen, while its prolific nature ensures high yields throughout the growing season. Additionally, Waltham 29 produces side shoots after the main harvest, further extending its productivity and making it an excellent choice for a fall crop.


    How To Grow

    Sowing: Broccoli seeds thrive in cooler conditions, so starting Waltham 29 broccoli seeds indoors 5-6 weeks before the last anticipated frost will lead to quicker growth. When the seedlings are approximately 15 centimeters tall, and shortly before the last frost, plant them 30-60 centimeters apart in rows spaced 60-90 centimeters apart. For direct sowing, plant seeds 2.54 centimeters deep and 7.62 centimeters apart in full sun and nutrient-rich soil, about 2-3 weeks prior to the last expected spring frost. Germination can occur at temperatures as low as 4 degrees Celsius. For fall planting, directly sow seeds in late July or August. For companion planting benefits, consider planting broccoli alongside herbs, potatoes, or onions, while avoiding planting it with tomatoes or pole beans.

    Growing: Ensure young plants receive adequate water and remove any weeds. Mulching helps to prevent weed growth and regulate soil temperature, while multiple applications of fertilizer or compost may be necessary. In the event of several nights with temperatures below freezing, cover the plants. If they become top-heavy as they grow, provide stakes for support.

    Harvesting

    Harvesting: Gather the main head when it remains compact, and before the small buds start to unfold; trim at least 15 centimeters of the stem. Additional side shoots will emerge along the stem and can also be harvested. With favorable weather conditions, the plant will continue to produce over time.

    Seed Saving

    Seed Saving: Allowing Waltham 29 broccoli to set seeds requires a full growing season and may involve either overwintering the plants or providing adequate mulching. As broccoli can cross-pollinate with other cabbage family members like cauliflower, it's advisable to maintain isolation of at least 400 meters to prevent unintended crossbreeding. Once the flowers have bloomed and developed seed pods, allow them to dry before carefully removing from the plant. Separate the seeds from the pods and store them in a dry, cool location for up to five years. To save broccoli seeds, allow selected heads to bolt and produce yellow flowers that will eventually form pods. Once the entire plant has dried and become brittle, remove the seeds from the pods by gently pounding the plant material. Store the seeds in a cool, dark place for up to five years.
