Growth Stages

1

Seedling

3-4 weeks

Tiny seedlings with 2-4 true leaves appear 10-14 days after sowing. Leaves are narrow and gray-green.

Maintain consistent moisture and bright light. Thin seedlings to prevent damping off. Avoid overhead watering.

2

Vegetative

4-6 weeks

Young plants develop bushy growth with narrow, lance-shaped foliage. Plants reach 6-12 inches tall with multiple stems forming.

Pinch growing tips when 4-6 inches tall to encourage bushier growth and more flower stems. Water moderately and ensure good air circulation.

3

Budding

2-3 weeks

Flower buds begin forming at stem tips; visible as tight, pointed green structures surrounded by leafy bracts (sepals).

Maintain consistent watering and apply balanced fertilizer (10-10-10) every 2-3 weeks. Remove any side buds on main stems if large exhibition flowers are desired.

4

Flowering

8-12 weeks (peak bloom) or longer with deadheading

Large ruffled double flowers open, revealing dense, layered scarlet-red petals. Flowers are highly fragrant and can persist 3-4 weeks per bloom.

Deadhead spent flowers to encourage continuous blooming. Stake tall stems if needed. Maintain even moisture and continue fertilizing.

5

Senescence/Dormancy

Variable by climate

In fall or when temperatures drop, flowering slows and foliage may fade. Plant enters dormancy in cold climates.

In mild zones, plants may overwinter; mulch base in late fall. In cold zones, treat as annual and allow plants to finish their cycle.

Harvest Tips

Cut stems in early morning when flowers are fully open but still fresh. Cut stems at a 45-degree angle just above a leaf node. Remove lower foliage below the waterline to prevent bacterial growth. Carnations are long-lasting cut flowers and can remain fresh in a vase for 2-3 weeks. For best longevity, use floral preservative in vase water and change water every 2-3 days.

Fun Facts

  • 🌱 Chabaud carnations are named after the Chabaud family, French flower breeders who developed this strain in the 1800s for their superior size, color, and fragrance.
  • 🌱 Carnations are one of the oldest cultivated flowers, with evidence of their cultivation dating back over 2,000 years; the scarlet color symbolizes admiration and deep love in the Victorian flower language.
  • 🌱 The double petals in Chabaud's Giant Scarlet result from selective breeding that converts stamens into petals, which is why they are sometimes sterile and reproduce best from cuttings rather than seeds.
