In British gardens, it has long been a favourite peat- 
earth trailing shrub, requiring an airy situation. It does 
not thrive in the immediate vicinity of London, nor where 
it is much sheltered ; but, either on rockwork, in beds of dry peat, or in 
moist peat, it grows with great luxuriance, and occasionally ripens fruit.
