Pelargonium zonale, commonly known as the Horseshoe Geranium, is a perennial plant often grown as an annual in cooler climates. It typically features a bushy, upright growth habit with rounded, slightly lobed leaves that have distinct dark horseshoe-shaped markings. The plant produces clusters of bright, showy flowers in various colors, including red, pink, white, and purple. The flowers are five-petaled and can appear in single or double forms. The stems are succulent and can become woody at the base with age.
Known Range:
Pelargonium zonale is native to South Africa but has been widely cultivated around the world. It thrives in temperate regions and is a popular choice for gardens, balconies, and as houseplants in many parts of Europe, North America, Australia, and Asia.
Care Requirements:
Light: Prefers full sun but can tolerate partial shade. At least 6 hours of sunlight per day is ideal for optimal flowering.
Water: Moderate watering needs. The soil should be kept consistently moist but not waterlogged. Allow the top inch of soil to dry out between waterings.
Soil: Well-draining soil is essential. A mix of garden soil, peat, and perlite is recommended.
Temperature: Thrives in temperatures between 60-75°F (15-24°C). Protect from frost; in colder regions, it can be brought indoors during the winter months.
Fertilization: Feed with a balanced, water-soluble fertilizer every 2-4 weeks during the growing season (spring and summer).
Pruning: Regular deadheading of spent flowers encourages more blooms. Trim back leggy growth to maintain a bushy shape.
Pests and Diseases: Watch for common pests such as aphids, whiteflies, and spider mites. Fungal diseases like botrytis and root rot can occur in overly wet conditions.
