From the botanical name for walnut trees, Juglans, which were first introduced to British shores by the Romans. The Latin name comes from Roman mythology where it was said that Jupiter, the king of the gods, also known as Jove, lived on walnuts while on the Earth. The full botanical name of the English walnut is Juglans regia, meaning the royal nut of Jupiter. The trees had a long history in the wider area but the street was actually named, like the nearby Walnuts shopping centre, after The Walnuts, a large mansion off the High Street that was built by the Vinson family in the late 19thCentury. The gardens contained an avenue of walnut trees. The last tree in the immediate area was chopped down in 2015.
