Heirloom Broccoli Seeds: Nutrient-Rich Crowns for the Cool Season
Broccoli is a centerpiece of the healthy home garden, prized for its high concentration of vitamins and antioxidants. At Firefly Farm & Mercantile, we curate heirloom broccoli seeds that are specifically selected for their ability to thrive in the cool, crisp mornings of the Driftless Region. Unlike store-bought varieties that are bred for long-distance travel, our non-GMO seeds—ranging from classic "Calabrese" to unique "Romanesco"—provide tender, flavorful heads that are far superior in taste and nutrition.
Maximizing Your Harvest: Two Growing Windows
To get the best results in northern climates, broccoli should be treated as a shoulder-season crop. We focus on cold-hardy varieties that can be started indoors early for a spring harvest or sown in mid-summer for a spectacular fall crop. Because homegrown broccoli produces "side shoots" after the main head is harvested, our heirloom seeds offer a prolonged harvest window, ensuring you get the most out of every plant in your garden bed.
Quick Broccoli Growing Facts:
- Planting Window: Start indoors 6-8 weeks before the last frost, or sow in July/August for a fall harvest.
- Hardiness Zones: Ideal for USDA Zones 3-7.
- Soil Preference: Requires rich, loamy soil with a pH between 6.0 and 7.0 and consistent moisture.
- Pest Management: Broccoli is part of the Brassicaceae family; we recommend using floating row covers to protect young plants from cabbage moths and worms.
- Expert Tip: Don't just eat the heads! Broccoli leaves are edible, highly nutritious, and can be used just like kale or collard greens. Harvest them sparingly throughout the season for a continuous supply of greens.
