Regal Geranium

Regal Geranium (Pelargonium x domesticum)

Regal Geranium brings showy, ruffled flower clusters that instantly dress up patios, porches, and bright indoor spaces. Also known as Martha Washington Geranium and Lady Washington Geranium, it offers intense color and patterned petals that feel more like a boutique bloom than a basic bedding plant. It performs best when days are bright and nights are cooler, which helps trigger stronger flowering. Use it in containers where you can control drainage and placement, and it will reward you with a polished, high-impact display.

Distinctive Features

This tender pelargonium forms a compact, bushy mound of rounded, lightly crinkled green leaves topped with large flower clusters in shades of pink, purple, red, white, and bicolors, often with dramatic blotches or veining. Bloom is typically strongest in spring into early summer, and it can flower again when temperatures moderate, especially with good light. The plant is valued for its refined, almost orchid-like look, with petals that appear ruffled and richly patterned. It is best treated as a container centerpiece because consistent drainage and airflow help keep it looking clean and vigorous.

Growing Conditions

• Sun: Full sun to part shade outdoors, or very bright light indoors, with protection from hot, intense afternoon sun in warm climates.
• Soil: Well-drained potting mix or garden soil that drains freely, and avoid heavy, wet soils.
• Water: Water thoroughly, then let the top of the mix dry slightly before watering again, because constantly wet roots reduce performance.
• USDA Zones: USDA Zones 10 to 11.
• Temperature: Prefers moderate days and cooler nights, and flowering often drops during hot, humid stretches.
• Airflow: Provide spacing and airflow to help reduce stress and keep foliage and blooms cleaner.

Ideal Uses

• Focal Point: Feature it in a decorative pot where the bold, patterned blooms become the main visual moment on a porch or patio.
• Containers: Use in patio pots and window boxes for a tailored look and easier control of moisture and drainage.
• Entry Styling: Place near doors and walkways for an upscale, welcoming display during the peak bloom season.
• Indoor Color: Grow near a bright window to bring vivid bloom color indoors when light and temperatures are suitable.
• Seasonal Displays: Pair with trailing accents and foliage plants for spring container combinations that look finished and intentional.

Low Maintenance Care

• Deadheading: Remove spent flower clusters to keep the plant tidy and encourage more blooming.
• Watering: Avoid overwatering and never leave containers sitting in water, because soggy conditions can lead to decline.
• Feeding: Feed lightly during active growth with a balanced fertilizer, especially in containers.
• Pruning: Pinch or trim stems to maintain a compact shape and promote fuller branching.
• Overwintering: In cold climates, bring indoors before frost and keep in bright light with cooler temperatures for best results.

Why Choose Regal Geranium?
