Dianthus chinensis 'Picotee'

flower

Picotee Bicolor is a charming variety of Chinese pink featuring delicate, ruffled petals with contrasting colored edges that create a distinctive two-tone effect. These compact, bushy plants produce abundant fragrant flowers that bloom prolifically throughout the growing season. The bicolor pattern—typically white or pale centers with darker pink, red, or purple picoted (edged) margins—makes them popular ornamental additions to gardens, containers, and cut flower arrangements.

Growth Stages

1

Seed Germination

7-14 days

Tiny seedlings emerge with cotyledons visible. Light and consistent moisture are critical.

Maintain soil temperature of 65-75°F. Keep soil surface moist but not soggy. Provide bright indirect light. Thin seedlings to appropriate spacing once first true leaves appear.

2

Seedling Development

3-4 weeks

True leaves emerge and plant develops a small rosette of narrow, blue-green foliage.

Provide bright light to prevent leggy growth. Gradually reduce watering frequency. Fertilize weekly with diluted balanced fertilizer. Begin hardening off if starting indoors.

3

Vegetative Growth

4-6 weeks

Plant develops bushy, mounding form with dense foliage. Height reaches 10-18 inches depending on variety.

Pinch growing tips to encourage bushier growth and more flower buds. Maintain consistent moisture and bright light. Apply balanced fertilizer every 2 weeks. Thin to final spacing.

4

Flowering

8-12 weeks or until frost

Small, fragrant flowers with distinctive picoted edges appear in profusion. Blooms range from single to semi-double forms.

Deadhead spent flowers regularly to encourage continuous blooming. Water consistently. Switch to low-nitrogen, higher-phosphorus fertilizer to promote flowering. Provide afternoon shade in hot climates.

5

Late Season/Decline

Variable based on climate

Flowering slows as temperatures cool or heat increases. Foliage may become less vigorous.

Continue deadheading to extend bloom time. Reduce fertilization. In cool climates, may recover with renewed blooming in fall. Tolerates light frost.
