The English language is funny. Sometimes we use the same word for completely different things; you know, just to make things a little more confusing.
Such is the case for nasturtium. Nasturtium can refer to the plant genus, which is the genus of seven plant species in the Brassicaceae family. The nasturtium we’re concerned about is the Tropaeolaceae, which is commonly known as nasturtium.
It is also the genus of almost 80 species of flowering plants, some of which can survive the winter at altitudes of 10,000 feet and up.
