History

Kirke's Blue was named by Joseph Kirke, a nurseryman from the Brompton district of London who first propagated it in the 1830s and subsequently promoted it. However its origins are unknown - Kirke stated he first saw the fruit for sale on a market stall and tracked down the original tree to Norfolk, but this is not certain. It soon became a popular variety in Victorian gardens.
