The Nasturtium
Nasturtium, known scientifically as Tropaeolum majus, is a flowering plant native to South America, particularly Peru and Bolivia. Introduced to Europe in the 16th century, its popularity quickly spread across the globe due to its vibrant blooms and edible qualities. The name "nasturtium" originates from the Latin word "nasus tortus," meaning twisted nose, referring to the peppery scent and flavor of its leaves and flowers.
Scientific Name - Tropaeolum majus
Cultivating nasturtiums is relatively straightforward, making them a favorite among novice and experienced gardeners alike. They thrive in well-draining soil with full sun to partial shade exposure. However, they can tolerate various soil types and are often found cascading over walls, hanging baskets, or climbing trellises. Nasturtiums require minimal care once established, making them ideal for low-maintenance gardens. Regular watering is essential, but they are relatively drought-tolerant once mature.
Here are some best planting and gardening practices for nasturtiums:
- Plant seeds directly in the ground after the last frost date in your area.
- Space seeds or seedlings approximately 10 to 12 inches apart to allow for ample spreading.
- Water consistently, keeping the soil evenly moist but not waterlogged.
- Mulch around plants to retain moisture and suppress weeds.
- Provide support for climbing varieties by installing trellises or stakes.
- Deadhead spent flowers regularly to encourage continuous blooming.
- Fertilize sparingly, as too much fertilizer can result in excessive foliage growth at the expense of flowers.
- Control aphids and caterpillars, which are common pests, by handpicking or using organic insecticidal soap.
- Harvest leaves and flowers for culinary use, adding a peppery flavor to salads, sandwiches, or garnishes.
Following these planting and gardening practices will ensure robust growth and prolific flowering of nasturtiums, adding color and flavor to any garden setting.
