📏

Spacing: 12 inches

📅

Days to maturity: Flowering begins within 60-90 days of planting; full mature size reached in 12-18 months

🌱

Planting depth: Plant crown at or slightly above soil level; avoid burying the crown as this can cause rot

Growth Stages

Establishment

4-6 weeks

Small transplants or newly divided plants establish root systems and begin leaf production

Keep soil consistently moist, protect from wind and excessive sun exposure, mulch lightly around the base (avoid piling on crown)

Vegetative Growth

8-12 weeks

Plant develops a dense mound of colorful foliage; leaves expand and deepen in color as temperatures cool

Water regularly, remove any dead or damaged leaves, foliage color intensifies in cooler months

Flowering

4-8 weeks (spring to early summer)

Delicate bell-shaped flowers emerge on tall, thin stems above the foliage in colors ranging from coral, red, pink, to white

Deadhead spent flowers to encourage continued blooming, provide consistent moisture, stake tall varieties if needed

Post-Bloom Dormancy

Summer through fall, variable

Flowers fade and plants enter a period of reduced growth; foliage remains ornamental

Cut back flowering stems after bloom ends, reduce watering frequency, divide overcrowded plants in fall

Winter Dormancy

3-4 months

Plants go semi-dormant; foliage may persist but growth slows significantly

Minimal watering, do not fertilize, apply light mulch in cold regions, remove winter debris
