How to grow Kirke's Blue plum trees

Kirke's Blue would almost certainly have become a popular commercial variety had it not been for its relatively light cropping. However for the gardener this can be an advantage because light-cropping plums often have the richest and most intense flavours.

The tree is of average vigour and tends to grow in a spreading fashion. This and the potential excellence of flavour make it a good choice for wall-training on a south-facing wall.

Historical details

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.
