Porterweed Dwarf Red #3 Care Guide

Introduction

Porterweed Dwarf Red (Stachytarpheta frantzii 'Dwarf Red') is a compact tropical perennial producing long, slender spikes of small red flowers nearly year-round. It is an easy warm-season plant that thrives in Florida's heat and humidity and is a top hummingbird and butterfly attractor. 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 and hummingbird gardens, borders, and tropical landscapes. Prune lightly to encourage bushier growth and more blooms. The red flowers are especially attractive to 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.
