A Storied Heritage of History and Etymology

Nasturtiums carry a fascinating backstory:

• “Nose-Twisters” and Roman Shields: The common name “nasturtium” stems from Latin roots meaning “nose-twister,” a humorous nod to the pungent, peppery kick of the edible leaves. Meanwhile, the genus name Tropaeolum was coined by Carl Linnaeus, who was reminded of an ancient Roman tropaeum (a victory pole hung with captured enemy armor). To Linnaeus, the round leaves resembled shields, while the brilliant crimson blossoms looked like blood-stained helmets!
• Culinary Tradition: The entire plant is famously edible. Young leaves add a zesty, peppery bite to salads, flowers make stunning gourmet garnishes, and the green seeds can even be pickled as a delicious, budget-friendly substitute for capers.

Garden Performance and Wildlife Value

Empress of India delivers brilliant color with minimal fuss:

• The Secret to Blooms (Lean Soil): Unlike many garden plants, nasturtiums actually prefer poor, sandy soil. Avoid fertilizing them, as extra nutrients will only result in a wall of lush green leaves with very few flowers!
• Container and Pollinator Star: Its neat, compact 16-inch stature looks stunning spilling over pots and window boxes while eagerly welcoming bees to your yard.

Growing and Care Tips

Getting your nasturtiums off to a great start involves a little seed prep:

1. Seed Prep (Scarification & Soaking): Because nasturtium seeds have a hard protective shell, lightly rub one side of each seed with sandpaper (scarification) and soak them in warm water overnight. (Note: While some gardeners swear by chilling seeds in moist sand for 30 days, direct sowing after scarifying and soaking in early spring yields wonderful results once soil warms!) Plant seeds just below the surface; germination takes 7 to 14 days.
2. Maintenance: Water seedlings regularly until established. Mature plants handle dry spells and poor soils with ease. Deadhead spent flowers to prolong the blooming season.
