Growth Stages

1

Seedling

2-3 weeks

Cotyledons emerge with distinctive rounded seed leaves; true leaves appear within 1-2 weeks.

Keep soil consistently moist but not waterlogged. Provide bright light and maintain warmth (65-70°F). Thin seedlings or pot on as needed.

2

Vegetative Growth

3-4 weeks

Plant develops bushy foliage with round, shield-shaped green leaves. Compact growth habit; minimal flowers yet.

Water moderately and allow soil to dry between waterings. Pinch stems early if desired to promote bushier form. Provide full sun for compact growth.

3

Budding

1-2 weeks

Flower buds form in leaf axils; buds appear as small rounded knobs with long spurs characteristic of nasturtiums.

Maintain consistent watering without overdoing it. Reduce nitrogen fertilizer; use balanced or phosphorus-rich fertilizer if needed. Ensure adequate sunlight.

4

Flowering

6-12+ weeks

Vibrant crimson-red and golden-yellow bicolored flowers open continuously. Flowers are trumpet-shaped with prominent spurs.

Deadhead spent flowers to encourage continuous blooming. Water regularly but allow some drying between waterings. Monitor for pests attracted to flowers.

5

Seed Development & Decline

Until frost or end of season

If flowers are not deadheaded, round seed pods develop; plant may slow flowering and vigor declines as seeds mature.

Allow some flowers to set seed if desired for self-sowing. In warm climates, plant may continue flowering. Cool fall temperatures signal end of season.

Harvest Tips

Flowers are edible and can be harvested anytime they fully open; pick in morning for best flavor and appearance. Seeds (seed pods) can be harvested when green and pickled, or left to mature and dry for next season's planting. Leaves are also edible with a peppery flavor.

Fun Facts

  • 🌱 Nasturtiums are native to South America and were named by Carl Linnaeus; 'Tropaeolum' derives from the Greek word 'tropaion' (trophy), as the round leaves resemble shields and the spurred flowers resemble helmets.
  • 🌱 The spurred flowers are an evolutionary adaptation for pollination by long-beaked hummingbirds and insects in their native habitat; the spur holds nectar at its tip.
  • 🌱 Both flowers and seed pods are edible—green seed pods can be pickled as a 'poor man's capers' substitute, and leaves contain glucosinolates similar to those in mustard and cabbage.
