Growth Stages

1

Establishment

4-6 weeks

Young plant focuses on root development and vegetative growth; minimal flowers

Keep soil consistently moist but not waterlogged. Provide stake support if needed. Begin light fertilizing every 2-3 weeks.

2

Vegetative Growth

6-8 weeks

Plant develops bushy, multi-branched form with bronze-tinted leaves; flower buds begin to form

Pinch back growing tips to encourage bushiness and branching. Apply balanced fertilizer monthly. Maintain consistent moisture.

3

Early Flowering

4-6 weeks

First tubular red-orange flowers appear at branch tips; plant reaches mature height

Continue moderate fertilizing with bloom-promoting fertilizer (higher phosphorus). Deadhead spent flowers to encourage more blooms. Water regularly.

4

Peak Blooming

8-12 weeks or more

Profusion of bright red-orange flowers cover the plant; dark berries begin to develop; foliage may show bronze coloring

Maintain regular watering and fertilizing schedule. Deadhead to extend blooming. Watch for pests; hummingbirds and butterflies frequent the blooms.

5

Winter Dormancy

3-4 months (November-February)

In zones 8b-9, plant may lose leaves or die back; in warmer zones, growth slows significantly

In cool zones, cut back by one-third in late fall. Reduce watering and fertilizing. Provide frost protection if temperatures drop below 28°F. In warm zones, light pruning is optional.
