Starship Scarlet Cardinal Flower

Starship Scarlet Bronze Leaf Cardinal Flower (Lobelia x speciosa)

Starship Scarlet Bronze Leaf Cardinal Flower delivers bold red flower spikes in summer while adding rich, bronzy foliage that keeps the planting looking finished. The upright habit brings clean vertical structure without taking up much space, so it layers easily into borders. It shines in consistently moist beds, where it stays vigorous and keeps color coming into early fall. Hummingbirds and butterflies flock to the blooms, making it a strong pick for lively, pollinator-focused gardens.

Distinctive Features

This perennial lobelia forms a dense, upright clump with green leaves that develop noticeable bronze tones, especially in strong light. From midsummer into early fall, it produces tall spikes of vivid scarlet-red, tubular flowers that stand above the foliage and read clearly from a distance. The overall habit is columnar to upright-mounding, giving borders a structured look without a heavy mass. It performs best where soil stays evenly moist, and it can struggle if allowed to dry out during hot weather.

Growing Conditions

• Sun: Full sun to part shade, with brighter light supporting best flowering and stronger bronze foliage tones.
• Soil: Fertile, moisture-retentive, well-drained soil, and it also tolerates wetter soils in rain garden settings.
• Water: Medium to wet, keep soil consistently moist through the growing season.
• USDA Zones: 6 to 10.
• Mature Size: About 20 to 28 inches tall and 16 to 22 inches wide.

Ideal Uses

• Focal Point: Plant in a small group as a focal point so the scarlet spikes rise above midsummer plantings and pull the border together.
• Moist Borders: Use in consistently moist beds where flowering stays strong through summer.
• Rain Gardens: Place in rain garden zones that stay damp but still drain between storms.
• Pond and Stream Edges: Plant near water features where soil moisture stays reliable without constant hand watering.
• Pollinator Gardens: Add to nectar-focused plantings to support hummingbirds, butterflies, and bees.

Low Maintenance Care

• Watering: Water during dry spells, since consistent moisture supports taller stems and longer bloom.
• Deadheading: Remove spent flower spikes to encourage continued flowering and keep the plant tidy.
• Mulching: Mulch to conserve moisture and moderate soil temperature, keeping mulch off the crown.
• Feeding: Feed lightly in spring if soil is lean, since overly rich feeding can push softer growth.
• Cleanup: Cut back stems after frost or in early spring before new growth begins.
