Growth Stages

1

Germination

7-14 days

Tiny seedlings emerge with cotyledons (seed leaves); plants are delicate and pale green

Keep soil consistently moist but not soggy. Provide bright, indirect light. Thin seedlings to proper spacing once they develop true leaves.

2

Vegetative Growth

2-3 weeks

Plant develops compound leaves and a dense, mounding habit; no blooms yet

Maintain moderate watering. Once established, reduce watering frequency. Pinch back growing tips if you want bushier plants. Begin fertilizing lightly every 2-3 weeks.

3

Early Flowering

1-2 weeks

First tiny flower clusters appear at branch tips; plant is still actively growing

Continue regular watering and weekly fertilizing with diluted liquid fertilizer. Deadhead spent flowers to encourage more blooming.

4

Peak Bloom

6-10 weeks

Plant is fully covered with dense clusters of fragrant flowers; mounding growth habit is pronounced

Deadhead regularly to maintain continuous flowering. Water consistently. In heat, provide afternoon shade and increase watering frequency. Fertilize weekly with balanced or bloom-promoting fertilizer.

5

Late Season/Decline

Variable; until first frost

Flowering may slow or plants may become leggy in mid-summer heat; can rejuvenate in fall

In hot climates, cut plants back by half in summer to rejuvenate. Resume deadheading and regular care. In cool climates, blooming continues until frost.

Fun Facts

  • 🌱 The 'Wonderland' series was specifically bred to be extra compact and floriferous, making it one of the best dwarf varieties for tight spaces and containers.
