Garden nasturtium
Also known as: Climbing nasturtium, Monks cress
The garden nasturtium is often associated with the "Elizabeth Linnaeus Phenomenon", an optical illusion that makes the contrasting orange flowers and green foliage appear to flash brightly as it shakes in the wind. Garden nasturtium is cultivated as an ornamental plant. The disc-shaped leaves and seed pods are edible, usually getting used as garnishes and dressings.
