Heartthrob™ Hollywood Hibiscus (Hibiscus rosa-sinensis 'RH-10') showcases brilliant yellow-orange flowers with pink-red centers that emerge through warm seasons. It generally reaches three to four feet in height, bringing a lively accent to garden beds or balcony containers. We’ve observed that its extended bloom period delivers consistent color for outdoor spaces seeking a tropical touch. This variety’s intense hue and glossy foliage create a dramatic statement unlike any other hibiscus plant.

Heartthrob™ remains evergreen in frost-free areas and attracts pollinators with its broad, open blooms. Deer usually avoid nibbling on its leaves, and it adapts well to humidity and heat when properly cared for. We’ve noted minimal issues with pests or disease, making it a reliable option for low-maintenance gardening. Consider mass plantings for a stunning hedge, incorporate it into borders for a bold display, or use a single specimen in a container as a focal point.

Heartthrob™ Hollywood Hibiscus Care

Plant this hibiscus in fertile, well-draining soil that trends slightly acidic to neutral in pH. Full sun encourages the best flower production, though moderate afternoon shade helps in regions with intense heat. Water deeply when the top inch of soil starts to dry, avoiding standing water. A regular application of balanced fertilizer during the growing season supports steady growth and rich blooms.

In colder climates, prune back any damaged stems and bring container-grown plants indoors before frost arrives. We recommend removing spent flowers to maintain a clean appearance, though heavy pruning is rarely necessary for young plants. A thin layer of mulch around the root zone helps conserve moisture and insulates the base in cooler weather. In colder areas, keep container-grown plants in a sunny spot indoors during winter and water sparingly to prevent waterlogged roots. Containers require proper drainage to support healthy root systems.

Heartthrob™ Hollywood Hibiscus Spacing

Leave four feet between each shrub for optimal airflow and growth. Group them closer when creating a hedge, but be prepared to prune as they develop. A 16-inch pot works well for a new plant, and upgrading to larger containers in subsequent seasons helps accommodate the expanding root system.
