Nasturtium 'Empress of India' (Tropaeolum majus): Deep Scarlet Double Blooms

Overview

Tropaeolum majus 'Empress of India' is a classic heirloom nasturtium forming a neat 12-inch mound. Its standout feature is the double, deep scarlet flowers that appear from summer into fall. Like all nasturtiums, the rounded leaves and five-petaled blossoms are edible with a pleasant peppery flavor. This South American native brings vintage charm to cottage gardens, herb beds, and containers.

Growing Conditions

Full sun and moist, well-drained soil are ideal. Lean soil promotes heavier flowering. Tolerates light shade but with reduced bloom. Avoid over-fertilizing, which leads to excessive foliage growth.

Care and Maintenance

Sow seeds indoors 4-6 weeks before last frost or direct-sow after danger of frost. Water consistently until established. Deadhead to prolong flowering. Plants are fast-growing and low-maintenance.

Common Problems

Potential pests include caterpillars, flea beetles, aphids, slugs, whiteflies, and viruses. Monitor regularly and treat organically if needed.
