Growth Stages

1

Seedling

2-3 weeks

True leaves emerge 7-10 days after sowing; plants develop 2-3 sets of leaves

Keep soil moist but not soggy. Provide good light and airflow to prevent damping off. Thin seedlings to proper spacing early.

2

Vegetative Growth

2-3 weeks

Plant develops multiple stems and leaves, forming a bushy plant with deep green foliage

Maintain consistent moisture and apply balanced fertilizer every 2-3 weeks. Mulch around plants to retain moisture and keep soil cool.

3

Head Formation

1-2 weeks

Central head forms with small florets clustered at the top, accompanied by side shoots with leaves

Increase nitrogen feeding to support head development. Monitor for pests and diseases. Ensure consistent watering.

4

Harvest-Ready

1-2 weeks

Main central head reaches 3-5 inches in length with tight florets; side shoots begin to develop below main head

Check plants daily once heads form. Harvest promptly to encourage side shoot production. Keep plants cool with shade cloth if temperatures exceed 75°F.

5

Secondary Harvest

2-4 weeks

Multiple side shoots with smaller heads and tender leaves develop after main head is harvested

Continue watering and light fertilizing. Harvest side shoots regularly to promote further branching and extend harvest season.

Uses

🍳

Sautéed greens and florets

Culinary

Rapini Apollo's tender shoots and small florets are delicious sautéed with garlic and olive oil. The slightly bitter flavor pairs well with pasta, grains, and roasted meats. [source]

🍳

Raw salads and appetizers

Culinary

Young, tender leaves and florets can be eaten raw in salads or served as crudités. The mild bitterness adds complexity to mixed greens. [source]

💊

Glucosinolate-rich crucifer

Medicinal

Like all brassicas, rapini contains glucosinolates that may support detoxification and have anti-inflammatory properties. Cooking reduces these compounds. [source]

💊

Nutritional powerhouse

Medicinal

High in vitamins A, C, K, folate, and minerals including iron and calcium. Supports bone health, immune function, and antioxidant protection. [source]

🏠

Spring and fall succession cropping

Household

Apollo's short 45-60 day maturity makes it ideal for multiple plantings throughout the season to ensure continuous harvest and fresh supply. [source]

Harvest Tips

Harvest the central head when it reaches 3-5 inches tall, before florets begin to flower and open. Cut with a sharp knife 1-2 inches below the head. Harvest in the morning when plants are crisp. Regular harvesting encourages prolific side shoot production for 2-4 additional weeks. Side shoots can be harvested with 2-3 leaves attached for maximum tenderness.

Fun Facts

  • 🌱 Rapini Apollo is a relatively new cultivar developed for early maturity and exceptional side shoot production, making it more prolific than traditional rapini varieties.
  • 🌱 The name 'broccoli rabe' comes from the Italian 'rapa,' meaning turnip, because it was traditionally grown as a turnip crop before the emphasis shifted to the florets and shoots.
  • 🌱 Rapini is one of the oldest cultivated brassicas, dating back to ancient Roman times, and remains a staple in Mediterranean and Asian cuisines.
