Hibiscus coccineus (Scarlet Rose Mallow)
Scarlet Rose Mallow, American Scarlet Rose Mallow, Swamp Hibiscus, Crimson Rosemallow, Wild Red Mallow, Texas Star Hibiscus
Vigorous, Hibiscus coccineus (Scarlet Rose Mallow) is a woody-based perennial noted for its 5-petaled, bright crimson red flowers, up to 3-5 in. across (7-12 cm). Blooming from mid-summer to early fall, the eye-catching flowers are adorned with conspicuous, protruding, creamy-white to pale yellow tubes of stamens. But even without these gorgeous blooms, this plant is worth growing for its shiny, palmately divided, deep green leaves.
- Typically grows with an upright habit, up to 3-6 ft. tall (90-180 cm) and 2-3 ft. wide (60-90 cm).
- Thrives in full sun or part shade in average, medium to wet soils. Tolerates summer heat and humidity. Site in locations protected from wind to minimize the risk of wind burn.
- Fairly pest and disease free. Watch for leaf spots, blights, rusts, canker, and Japanese beetles. Deer resistant.
- Plant in shrub borders for dramatic summer blooms. Great flowering shrub for bog gardens, rain gardens, along streams or ponds.
- Cut back stems to approximately 3-4 in. in late autumn (7-10 cm). Plants will benefit from regular fertilization during the growing season.
- Native to the southeastern United States.
