Native to Azerbaijan and northern Iran, Silene has been grown in the UK since the middle of the 19th century.
It's a charming little alpine that should be planted in a free-draining but moisture retentive soil. It is best sited on a ledge so the roots are shaded by the surrounding rocks and the stems can trail downwards, displaying the deep pink to reddish-purple flowers that are produced from July to October.
Growth continues throughout the summer and although this plant can tolerate some drought, it does better if the soil is not allowed to dry out completely.
A thick mulch of grit will keep moisture away from the foliage in winter.
