About

Cotoneaster simonsii (syn. Cotoneaster newryensis), the Himalayan cotoneaster, is a species of flowering plant in the family Rosaceae. It is native to Nepal, the eastern Himalayas, Assam, and Myanmar, and has been introduced to a number of locales in Europe, the west coast of North America, and Australia as a garden escapee. The Royal Horticultural Society considers it to be an undesirable invasive non-native species.

How to grow it

As its synonym C. newryensis, it was first raised at Thomas Smith's Daisy Hill Nursery in Ireland from where it was moved to be distributed by Barbier Nursery in France. It appeared at Lemoine nursery catalogue by 1911 in Nancy, France.

The plant has its detractors, such as garden designer Russell Page: "It is a horrid ungainly plant which I would usually exclude from any garden."
