Embrace the Beauty of Tricolor Nasturtium with Its Spectacular Floral Display
Tropaeolum tricolor, commonly known as Tricolor Nasturtium, Bolivian Nasturtium, or Three-colored Indian Cress, belongs to the family Tropaeolaceae. Tricolor Nasturtium is an enchanting perennial climber that captivates with its profusion of tricolor flowers. It is native to Chile, where it is called “Soldadito Rojo” and “Relicario.” This captivating climber has gained popularity as an ornamental plant due to its striking appearance and extended flowering period.
Characteristics of Leaves and Flowers: Tricolor Nasturtium features soft, bright green leaves with deep lobes, creating an attractive backdrop for its exquisite flowers. The small yellow flowers, measuring about 1 inch (3 cm) in length, bloom singularly in the leaf axils. Each flower is adorned with a showy purple-tipped, orange-red calyx and a long red or purple spur, adding to its allure. The narrow funnel-shaped flowers persist for months, forming a vibrant floral display. After the flowers fall, the sepals turn brown and enclose the dark brown seeds, enhancing the plant’s visual appeal.
Cultivation of Tropaeolum tricolor:
Sunlight: Tricolor Nasturtium thrives in full sun exposure, which allows it to showcase its vibrant colors to the fullest. However, it can also tolerate light shade in regions with hot summers.
Watering: Provide regular watering to keep the soil moist during the growing season. However, during the summer dormancy period, it is crucial to keep the tubers dry to prevent rotting.
Soil: Tropaeolum tricolor prefers well-drained, loamy soil that retains moisture without becoming waterlogged. It is essential to use lime-free soil for optimal growth.
Pest and Disease Control: Tricolor Nasturtium is generally resistant to pests and diseases. However, occasional monitoring is recommended to detect the presence of whiteflies or red spider mites. Prompt action through appropriate pest control measures can help maintain the plant’s health.
Tropaeolum tricolor can be propagated through two primary methods: seed propagation and tuber separation. Seeds can be sown to cultivate new plants, while tubers, which often form at the bottom of pots or emerge through drainage holes, can be separated during the summer dormancy period.
USDA Hardiness Zone: Tricolor Nasturtium is classified as a Zone 8 plant, indicating that it thrives in regions where the average minimum temperature does not fall below 10 to 20°F (-6 to -12°C). In colder regions, it is recommended to grow this plant under protective glass or in a greenhouse to prevent freezing.
