Traditional uses

Nemesia strumosa has no folk-medicine or culinary tradition to speak of. Its story is a horticultural one: this cheerful little annual was gathered from the wild hills of South Africa's Cape region and carried into European greenhouses in the nineteenth century, where breeders quickly fell for its snapdragon-shaped, jewel-toned flowers. Within a few generations it went from a wildflower on rocky Cape slopes to a staple of Victorian bedding schemes and, later, of window boxes and cottage borders everywhere. Its value has always been ornamental, brightening a garden bed the way a handful of confetti brightens a table.

Choose it when

When a border, window box, or patio pot needs to look like it has been dusted in confetti, from the first mild days of spring until summer's heat finally asks it to rest.

Did you know?

The genus name Nemesia borrows from the ancient Greek word nemesion, a name the physician Dioscorides once used for an unrelated snapdragon-like plant, simply because early botanists thought the flowers looked so similar.

Safety

Grown as a garden ornamental with no history of medicinal or culinary use; keep it away from children and pets who might be drawn to its bright blooms.
