Growth Stages

1

Seedling

2-3 weeks

Two round cotyledons emerge; first true leaves develop with distinctive palmate shape

Keep soil consistently moist. Provide bright indirect light. Thin seedlings to proper spacing. Avoid transplanting shock by hardening off gradually

2

Vegetative Growth

3-4 weeks

Trailing stems elongate rapidly with distinctive shield-shaped leaves. Variegated foliage becomes more pronounced

Water regularly but allow soil surface to dry slightly between waterings. Pinch stems to encourage bushier growth and trailing habit. Apply light balanced fertilizer monthly

3

Budding & Flowering

8-12 weeks (continuous throughout season)

Flower buds form in leaf axils; mahogany-red blooms with creamy-yellow edges emerge continuously

Maintain consistent moisture during flowering. Deadhead spent flowers to encourage continuous blooming. Reduce nitrogen to promote flowering over leaf growth

4

Peak Bloom

6-8 weeks

Plant is covered in vibrant two-toned flowers; trailing stems reach full length with dense foliage and blooms

Water deeply when top inch of soil is dry. Fertilize every 2-3 weeks with lower nitrogen formula. Monitor for pests attracted to lush growth

5

Maturity & Decline

Until frost or season end

Flowering may slow in extreme heat or with declining light. Seed pods develop after flowering if not deadheaded

In hot climates, provide afternoon shade to extend blooming. Continue deadheading to maintain vigor. Collect seeds for next year if desired

🏠

Companion Planting for Pest Control

Household

Nasturtiums act as trap crops, attracting aphids and other pests away from vegetable crops while repelling whiteflies and spider mites through their natural compounds. This sacrificial companion planting protects more valuable plants [source]

🌿

Trailing Container & Landscape Display

Ornamental

The striking mahogany-cream variegated flowers and cascading habit create stunning visual interest in hanging baskets, window boxes, and as ground cover in mixed borders. Long season of continuous blooms extends garden color into fall [source]

Fun Facts

  • 🌱 The name 'nasturtium' comes from Latin meaning 'nose-twister,' referring to the peppery, pungent aroma and spicy flavor that makes many people's noses twitch
  • 🌱 This variety's mahogany-cream coloring is achieved through natural pigments called anthocyanins and carotenoids, which also provide antioxidant benefits when consumed
