Warm-Season Annual
Nasturtium
Tropaeolum majus
A colorful annual with distinctive round foliage and vibrant red, orange and yellow flowers
Nasturtium is a fast-growing warm-season annual recognized for its rounded, shield-like green leaves and bright, long-spurred flowers. Blooms commonly appear in shades of yellow, orange and red and stand out clearly against the broad foliage. Depending on the variety, plants may develop a compact, spreading or trailing growth habit, making Nasturtium useful in annual flower plantings, borders, containers and pollinator-oriented landscapes.
Flower Characteristics
Why Plant Nasturtium?
Nasturtium combines distinctive foliage, vivid warm-season flowers and vigorous annual growth in an adaptable ornamental species.
Bright Summer Color
Showy flowers commonly appear in vivid shades of yellow, orange and red for strong warm-season color.
Distinctive Foliage
Nearly round leaves are carried on stalks attached near the center of the leaf, creating the characteristic parasol-like Nasturtium appearance.
Pollinator Interest
Bright, nectar-bearing flowers can attract bees and other visiting pollinators during the flowering season.
Versatile Growth Habit
Depending on the type, Nasturtiums may grow compactly, spread across the ground or develop longer trailing stems.
Where It Fits
Best Uses for Nasturtium
Nasturtium is particularly useful where vivid warm-season flowers and broad, distinctive foliage are desired.
Establishment & Management
Growing Nasturtium
Nasturtium establishes readily from its relatively large seed once frost danger has passed and growing conditions begin to warm.
Planting Window
Direct seed outdoors after danger of frost has passed. Nasturtium is a warm-season annual and performs best during frost-free growing conditions.
Sunlight
Full sun generally produces the strongest flowering. In very hot locations, some protection from intense afternoon sun can be beneficial.
Soil & Fertility
Use reasonably well-drained soil and avoid excessive fertility. Very rich soil can promote abundant foliage while reducing flower production.
Water Management
Provide consistent moisture during germination and early establishment, then avoid keeping established plants in persistently saturated soil.
Distinctive Annual
Easy to Recognize in Any Planting
Few annual flowers combine foliage and flower structure quite like Nasturtium. Rounded, parasol-like leaves form a dense green backdrop for brightly colored flowers with a characteristic rear spur. The result is a recognizable warm-season plant that provides both foliage texture and strong flower color.
