From Oregon to Cumbria
This is a Lewisia. A favourite alpine plant. But not from the Alps.
It grows on the north facing slopes of the Rocky Mountains in north-western U.SA. especially in Oregon and Washington State.
It is named after Meriwether Lewis the famous explorer who with his partner Clark first explored that part of the continent. He discovered the plant in 1810. The native tribes of the area had long used its bitter roots for medicinal purposes. In fact its other name is Bitterroot and the place where Lewis found it is called Bitterroot Mountain.
It is a long way from home but it seems very happy in a tub on my front driveway in Arnside.
