60. Persicaria campanulata (J.D. Hooker) Ronse Decraene POLYGONACEAE

This pink-flowered herbaceous plant is native to the Sino-Himalaya from Uttarakhand eastwards to western Yunnan. It was first found by Joseph Hooker in 1848 on the border of Eastern Nepal and Sikkim, and introduced to cultivation, via the Calcutta Botanic Garden, as a choice garden plant. It first flowered in a British garden in 1910, but has since escaped and become naturalised – especially in western Scotland, the West Country of England and in South-West Ireland.
