Broccoli

Broccoli (Brassica oleracea var. italica) is a cruciferous vegetable in the family Brassicaceae. It is known for its edible flower heads and stalks, which are high in nutrients. Broccoli is native to the Mediterranean region but is now cultivated worldwide.

Starting Broccoli Plants

To start broccoli plants:

1. Start seeds indoors 6-8 weeks before the last frost date in your area
2. Sow seeds 1/4 to 1/2 inch deep in seed starting trays or pots filled with seed starting mix
3. Keep soil moist but not soggy and maintain a temperature of 65-75°F (18-24°C)
4. Provide plenty of light, using grow lights if necessary
5. Harden off seedlings and transplant outdoors 2-4 weeks before the last frost date, when they have 4-5 true leaves

Broccoli can also be direct-seeded outdoors 2-3 weeks before the last frost date for spring planting, or in late summer for a fall harvest.

Harvesting Broccoli

Broccoli is typically ready to harvest 50-100 days after transplanting, depending on the variety. To harvest:

1. Cut the main head when it is fully developed, but before the individual florets begin to open
2. Make a clean cut with a sharp knife, about 5-6 inches below the head
3. After harvesting the main head, smaller side shoots will develop, which can be harvested for several weeks
4. Broccoli plants will continue to produce side shoots for several weeks after the main head is harvested.

Saving Broccoli Seeds

To save seeds from broccoli:

1. Allow the plant to flower and produce seed pods
2. Wait for the seed pods to turn brown and dry on the plant
3. Cut the seed pods from the plant and place them in a paper bag
4. Allow the pods to dry completely indoors for 1-2 weeks
5. Crush the pods to release the seeds
6. Store dried seeds in an airtight container in a cool, dry place

Common Broccoli Varieties

Some commonly grown broccoli varieties include:

• Calabrese: Large, blue-green heads with a dome shape; the most common type of broccoli
• Waltham 29: Reliable, cold-tolerant variety with medium-sized heads; good for fall crops
• Belstar: Heat-tolerant variety with tightly packed, blue-green heads; good for spring and summer crops
• Romanesco: Unique variety with spiraling, chartreuse heads; has a nutty, slightly sweet flavor

Uses as Food

Broccoli is a versatile vegetable that can be prepared in many ways:

• Steamed, boiled, or stir-fried as a side dish
• Used raw in salads or with dips
• Added to soups, stews, casseroles, and pasta dishes
• Roasted or grilled for a slightly smoky flavor
• Blended into smoothies or juices for added nutrients
• Broccoli is known for its high nutritional value, being rich in vitamin C, vitamin K, folate, and fiber. It also contains glucosinolates and sulforaphane, which may have potential health benefits.
