Growth Stages

1

Seedling

2-3 weeks

Tiny cotyledons emerge with first true leaves appearing within 7-10 days. Soil should remain moist but well-drained.

Thin seedlings to proper spacing at 2-3 true leaves to prevent crowding. Water gently to avoid disturbing tender seedlings.

2

Vegetative Growth

3-4 weeks

Plants develop rosette of deeply lobed green leaves; roots begin swelling underground. Purple coloring starts appearing on the root shoulder at the soil surface.

Maintain consistent watering and remove weeds regularly. Side-dress with compost if growth appears slow. Ensure roots are not exposed to light (which causes greening).

3

Root Development

2-3 weeks

Roots expand rapidly with distinct purple-top coloring intensifying. Leaves continue growing and become more abundant, suitable for harvest.

Water regularly and consistently. Apply 1-2 inches of mulch around plants to retain moisture and keep roots covered. Begin harvesting larger leaves if desired.

4

Maturity

1-2 weeks

Roots reach 2-3 inches in diameter with fully developed purple tops. Root texture becomes firmer and flavor profile peaks. Top greens are lush and tender.

Harvest roots when 2-3 inches in diameter for best flavor and texture. Continue watering to prevent root splitting. Roots can be left in ground for extended storage in cool climates.

5

Extended Storage

Variable

If left unharvested, roots may become woody and pithy; top greens may bolt in warm weather.

For storage, harvest before reaching 3+ inches diameter. Store roots in cool, humid environment (32-40°F) and use within 2-3 months.

Uses

🍳

Roasted Root Vegetable

Culinary

The sweet, mild roots can be roasted whole or cut into wedges, becoming tender and slightly caramelized. The mild flavor makes them suitable for both simple preparations and complex sauces. [source]

🍳

Nutritious Greens

Culinary

The tender, slightly peppery tops are rich in vitamins A, C, and K and can be sautéed, steamed, or added raw to salads. Young leaves are more tender than older mature foliage. [source]

🍳

Raw Snack or Salad

Culinary

Young, tender roots can be sliced thin and eaten raw with a light dressing, offering a crisp, slightly sweet texture similar to mild radishes. [source]

🏠

Ornamental Garden Crop

Household

The striking purple-and-white bicolor roots and lush green foliage make Purple Top Scarlet Queen visually appealing in raised beds and vegetable gardens, adding aesthetic interest. [source]

💊

Harvest Tips

Harvest roots when 2-3 inches in diameter (typically 50-70 days after planting) for peak tenderness and flavor. Gently pull or loosen soil first to avoid breaking roots. Harvest tops as needed once plants are established, or wait until roots are mature to harvest entire plant. Spring and fall crops generally taste milder and sweeter than summer-grown roots. Store roots in cool, humid conditions (32-40°F) in sand or peat moss; they keep 2-3 months. Top greens should be used within 1-2 days of harvest.

Fun Facts

  • 🌱 Purple Top Scarlet Queen is an heirloom variety that dates back to the 1800s, particularly popular in Victorian-era kitchen gardens for its dual purpose—roots and nutritious tops.
  • 🌱 The purple pigmentation comes from anthocyanin compounds, the same antioxidants found in blueberries and red cabbage, making this variety both nutritious and visually striking.
  • 🌱 Unlike many turnip varieties, Purple Top Scarlet Queen has a relatively mild, sweet flavor when harvested young, making it appealing to those who find traditional turnips too peppery or bitter.
