Growth Stages

1

Seedling

10-14 days

Tiny seed leaves emerge; plant develops first true leaves. Growth is slow initially.

Keep soil consistently moist but not waterlogged. Provide bright light (12-14 hours daily). Maintain 70-75°F for optimal germination.

2

Vegetative

2-3 weeks

Plant develops multiple stems and true leaves; begins forming a compact, bushy shape.

Harden off transplants gradually before planting outdoors. Pinch growing tips at 4-6 inches tall to encourage bushiness. Water regularly but avoid overhead irrigation.

3

Flowering (Early)

1-2 weeks

First flower buds appear; plant transitions from purely vegetative growth to reproductive phase.

Ensure consistent watering and full sun exposure. Apply balanced fertilizer weekly. Remove any damaged leaves.

4

Flowering (Peak)

8-12 weeks or until frost

Plant is covered with vibrant red semi-double flowers; continuous blooming throughout season with minimal deadheading needed.

Deadhead occasionally to encourage more flowers, though 'Profusion' is self-cleaning. Water at base of plant. Apply light fertilizer every 2-3 weeks. Remove diseased leaves promptly.

5

Decline/End of Season

Until first frost

Flowering slows as temperatures drop and frost approaches. Plant may show signs of stress from heat or disease.

Continue watering and light feeding until first frost. Pull up entire plant after frost kills it. Collect seeds if desired before discarding.

Harvest Tips

Profusion Red is an ornamental flower not typically harvested. For cut flowers, cut stems in early morning after dew dries. Cut just above a leaf node. Flowers last 7-10 days in a vase. Deadheading spent flowers encourages more blooms but is optional due to the cultivar's self-cleaning nature.

Fun Facts

  • 🌱 The 'Profusion' series was developed specifically for disease resistance and continuous self-cleaning blooms, requiring virtually no deadheading—a major advantage over traditional zinnias.
  • 🌱 Zinnias originated in Mexico and were named after Johann Gottfried Zinn, an 18th-century botanist, though they weren't widely cultivated in Europe until the 1800s.
  • 🌱 Profusion Red flowers can attract hummingbirds, butterflies, and bees simultaneously, making it one of the most beneficial flowers for pollinator-friendly gardens despite being an ornamental.
