Garden Use
Abundant, long-lasting blooms and a characteristic fragrance -- these are the major appeals of regal Geranium for gardeners and the main reason it is the most popularly sold plant in retail garden stores. It is frequently grown in containers on patios, windowsills, hanging pots, or in garden beds in groups as a statement plant.
Symbolism
Friendship, happiness and positive emotions
Interesting Facts
Regal Geranium, like many related species, are relatively resistant to deer. That's good news for enthusiasts of the flowers, but gardeners must still be on the lookout for caterpillars. Many species of the Lepidoptera insects (moths and butterflies) will happily munch away at regal Geranium leaves in their caterpillar form.
Name Story
Regal pelargonium: Members of the Pelargonium genus were originally classified with the Geranium genus. Now, though the scientific names have diverged, they are both often called "geraniums." To keep a common theme, though, botanist Johann Jacob Dellenius chose to call the new genus by the Greek word for "stork" while Geranium is Greek for "crane."

Soil Type
Water: Regal Geranium thrives in subtropical regions, needing regular moisture and moderate humidity. Water weekly to keep the soil evenly moist but not waterlogged. As an evergreen, regal Geranium benefits from consistent soil moisture for year-round foliage and flower display, especially when grown indoors.
Fertilize: Fertilize regal Geranium with high phosphorus fertilizers to enhance blooms. Use a balanced, water-soluble formula bi-weekly in growth season and monthly in winter. Apply half-strength to avoid harm, adjusting based on size. Seasonal feeding aligns with regal Geranium's metabolic cycle for optimal health.
Pruning: Regal Geranium thrives with regular pruning to maintain shape and enhance flowering. Prune in early spring or late winter, cutting back one-third and removing weak stems. Deadheading promotes longer blooms, while proper pruning improves air circulation and reduces disease, fostering a healthier plant.
Propagation: Regal Geranium is propagated via cuttings from healthy, disease-free, semi-ripe stems with multiple leaf nodes. Rooting hormone enhances success when planted in well-draining soil. Maintaining consistent moisture and warm temperatures is crucial for establishing a strong root system while handling cuttings carefully.
Repotting: Repot regal Geranium in early spring to support growth, using spacious containers every two to three years. After repotting, provide well-draining soil and avoid overwatering to prevent root rot. Bright, indirect light promotes recovery and enhances regal Geranium's vibrant blooms.
