Growth Stages

1

Seedling

2-3 weeks

True leaves emerge after 7-10 days; seedlings are small and delicate with one pair of cotyledons followed by thin, narrow true leaves

Keep soil moist but not waterlogged. Provide bright light to prevent leggy growth. Thin seedlings to proper spacing once they have 2-3 true leaves

2

Vegetative Growth

3-4 weeks

Plant develops multiple stems and a bushy, compact form with narrow, lance-shaped green foliage. Root system deepens and strengthens

Pinch out the growing tip when 4-6 inches tall to encourage bushier growth and more flower buds. Water moderately; avoid excessive fertilizer which promotes foliage over flowers

3

Budding

1-2 weeks

Flower buds form at the tips of branches; buds are tightly compressed spheres with papery bracts, initially green then showing color underneath

Continue moderate watering. Deadhead spent flowers to encourage more blooms. Support tall stems if needed with stakes

4

Flowering

6-8 weeks and beyond until frost

Distinctive double or semi-double flowers open in shades of blue, pink, red, white, or bi-colors. Each flower head is 1-2 inches across with delicate, fringed petals. Plant remains in continuous bloom

Deadhead regularly to extend bloom period. Water during dry spells but allow soil to dry between waterings. Flowers are excellent for cutting

5

Seed Development & End of Season

2-4 weeks before frost or heat decline

After flowering, seed heads form inside the papery bracts. Foliage may begin to decline as temperatures drop or heat increases

Allow some flowers to remain on the plant if you wish to collect seeds for next year. Harvest seed heads when they turn brown and papery. Plants may self-sow for next season

Harvest Tips

For cut flowers, harvest in the morning after dew dries but before heat of the day. Cut stems at a 45-degree angle just above a leaf node. Remove lower leaves that would sit below the waterline. Change water every 2-3 days. For seeds, allow flowers to dry on the plant, then collect seed heads when papery and brown; dry further indoors before storing. Cut flowers last 7-10 days in a vase
