5 Seeds Hibiscus hamabo (Yellow Hibiscus) Hardy Coastal Shrub

Hibiscus hamabo, also known as the Yellow Hibiscus or hardy coastal hibiscus, is a graceful flowering shrub prized for its soft yellow, cup-shaped blooms with deep maroon centers. This salt-tolerant, cold-hardy plant thrives near the coast or in sheltered inland gardens, offering a tropical look with remarkable resilience. Each seed produces a vigorous, upright shrub with attractive, rounded foliage that adds year-round structure and seasonal color to borders, hedges, or container displays.

These seeds are ideal for ornamental landscaping, whether planted as a specimen shrub, in mixed borders, or massed for a soft flowering hedge. The plant performs best in full sun to partial shade and prefers well-draining, loamy soil. Start seeds indoors in early spring or sow directly after the last frost, keeping the soil consistently moist for reliable germination. Once established, this low-maintenance shrub requires minimal care and rewards growers with weeks of delicate blooms.
