Trailing Nasturtium
Purple Emperor Nasturtium is a show-stopping edible ornamental that transforms throughout the season, opening as bold burgundy-purple blooms that soften into vintage dusty lavender-rose as temperatures shift. These semi-trailing vines reach 18 to 24 inches, making them perfect for cascading from containers or tumbling along garden edges. Both flowers and peppery leaves are fully edible, bringing shocking color and a spicy kick to salads and plates, while the green seed pods can be pickled into capers. Blooming prolifically from seed in just 50 to 60 days, this heirloom thrives in full sun and compact spaces, needing minimal fussing to deliver maximum impact.

What sets Purple Emperor apart is its stunning color evolution, those intense burgundy-purple petals gradually shift to a soft, powdery lavender-rose throughout the season, giving you a living reminder that gardens are always changing. The semi-trailing growth habit keeps it manageable at 18 to 24 inches while still producing those cascading vines of wine-colored blooms that make it genuinely one of the most beautiful edible ornamentals you can grow. Every part rewards you: flowers and leaves deliver genuine peppery flavor to refresh summer salads, and young seed pods transform into tangy pickled capers. Fast-maturing in 50 to 60 days from seed and needing only full sun and modest spacing, Purple Emperor proves that ornamental beauty and culinary function aren't mutually exclusive.
Purple Emperor works as both ornamental spectacle and edible component, making it unusually versatile in the kitchen and garden. The flowers and leaves bring peppery bite and dramatic color to fresh salads, while their visual intensity makes them ideal for garnishing plates where appearance matters as much as taste. The young green seed pods, a true delicacy, transform into homemade pickled capers that rival anything from a jar, capturing that salty-tangy profile that elevates cheese boards and fish dishes. This is a plant that earns space through sheer beauty while quietly delivering culinary rewards.
Harvest blooms and leaves continuously throughout the season once the plant is established, typically beginning around 50 to 60 days from sowing. Pinch flowers just above the base where they attach to the stem; they're most tender and flavor-rich in early morning. For pickled capers, harvest the young green seed pods when they're still small and tender, before they mature and harden, this is where the true culinary magic happens.
With its semi-trailing habit, Purple Emperor benefits from light pinching early in the season to encourage branching and a fuller cascade of vines. Once established, let it tumble naturally, the sprawling growth is part of its charm. Remove any dead or damaged foliage as you spot it, and trim back stems if they outgrow their space, though the 18 to 24 inch length is manageable in most settings.
