- Both the leaves and flowers of nasturtium are edible, with a distinctive peppery flavor similar to watercress.
- The pickled seed pods are sometimes called 'poor man's capers' and have been used as a substitute since the 18th century.
- Nasturtium leaves are exceptionally water-repellent — water beads up and rolls off, just like the lotus.
- Carl Linnaeus's daughter Elisabeth Christina reported that nasturtium flowers occasionally appeared to emit tiny sparks at twilight, a phenomenon now called the 'Elizabeth Linnaeus phenomenon.'
- Nasturtiums are 'trap crops' — gardeners plant them to attract aphids and cabbage white butterflies away from vegetables.
