Porterweed 'Giant Coral' #3 Care Guide

Introduction

Porterweed 'Giant Coral' (Stachytarpheta mutabilis 'Giant Coral') is a vigorous tropical perennial producing long, arching spikes of coral-pink flowers nearly year-round. It is an easy warm-season plant that thrives in Florida's heat and humidity and is one of the top butterfly and hummingbird attractors available. Available in a #3 container.

Growing conditions

• Light: Full sun to partial shade; best flowering in full sun.
• Water: Low to moderate; drought-tolerant once established.
• Soil: Well-draining soil; tolerates poor, sandy soils.
• Fertilizer: Little to no fertilizer needed; excess fertilizer reduces flowering.
• Season: Tropical perennial; blooms nearly year-round in South Florida; protect from frost in North Florida.

Planting tips

Plant in a sunny, well-drained location. Excellent for butterfly gardens, borders, and tropical landscapes. Prune lightly to encourage bushier growth and more blooms. The coral-pink flowers attract both butterflies and hummingbirds.

Troubleshooting

Frost damage

Foliage dies back in freezing temperatures. Cut back damaged growth in spring; roots typically survive and resprout.

Root rot

Overwatering or poor drainage. Reduce watering and ensure soil drains freely.

Leggy growth

Insufficient light. Move to a sunnier location and prune back to encourage compact growth.

Pet safety

Porterweed is non-toxic to pets and is generally considered safe around dogs and cats.
