Growth Stages

1

Seedling

2-3 weeks

Tiny green seedlings emerge with fine, needle-like cotyledons. First true leaves develop slowly and appear linear and delicate.

Maintain consistent moisture without waterlogging. Provide bright light to prevent leggy growth. Keep soil temperature around 70°F for best germination.

2

Vegetative Growth

3-4 weeks

Plant develops compact, bushy form with linear gray-green foliage. Multiple stems branch out, creating a mounded shape. Height remains 8-15 inches.

Water regularly at soil level. Pinch back growing tips once plants reach 4-6 inches to encourage bushier growth and more flower buds. Light fertilization every 2-3 weeks.

3

Budding & Early Flowering

2-3 weeks

Tight flower buds form at stem tips in clusters. Buds are small, elongated, and tightly packed before opening over several days.

Maintain consistent watering as flowering begins. Continue light feeding with balanced or slightly phosphorus-enriched fertilizer. Deadhead spent blooms regularly to encourage more flowers.

4

Peak Flowering

4-6 weeks or longer

Abundant crimson-red and white picotee flowers open, often creating a dense display of color. Blooms are typically 0.75-1 inch across, delicately fringed, and fragrant.

Deadhead frequently to maintain continuous blooming. Water during dry spells. Reduce nitrogen fertilizer if foliage becomes too lush at expense of flowers. Enjoy fragrance in morning or evening.

5

Extended Bloom & Decline

2-4 weeks before decline or through season if well-maintained

Flowering continues but may slow in peak summer heat or as days shorten. Some seed pods may form if flowers aren't deadheaded. Foliage may look tired in late season.

In hot climates, provide afternoon shade to extend blooming. Deadhead diligently. Consider light pruning to rejuvenate plants. In fall, plants may rebloom with cooler temperatures. Reduce watering slightly.

Harvest Tips

Crimson Picotee is primarily ornamental but can be cut for fresh arrangements. Cut stems in early morning when fully hydrated, choosing flowers at or just past the opening stage. Cut above a leaf node to encourage branching. Remove lower leaves that would sit below the waterline to extend vase life (5-7 days). Deadhead spent flowers on the plant regularly to promote continuous blooming throughout the season.
