How to tell it
A creeping or climbing fleshy plant. Nearly circular blue-green leaves, the stalk attached at the centre of the blade and veins radiating like wheel spokes, with water running off in round beads. Five-petalled flowers in yellow, orange or red, with a long curved spur behind.
What it is confused with
Madeira moneywort
Sibthorpia peregrina
Both line levada walls and have round leaves with the stalk attached in the middle. Madeira moneywort is tiny, two to four centimetres, with yellow flowers a few millimetres across; nasturtium has palm-sized leaves and large orange spurred flowers. Neither is dangerous, and only nasturtium is eaten.
What it is for
Leaves, flowers and buds are eaten in salads, with a peppery watercress taste, and the pickled buds have stood in for capers. It is one of the few plants in this guide whose identification is easy and whose use is real and current. Gather away from roads and treated ground.
Traditionally used as food. This is not permission to eat it.
Where it occurs
Each square is an area with recorded observations of this plant. The lighter background is the set of areas where any of the entries has been observed, and serves as a reference. Note what this is not: it is not where the plant lives, it is where people record it, so trails and towns always look fuller than the mountains. Data from GBIF.
