Paronychia kapela subsp. serpyllifolia
Paronychia kapela subsp. serpyllifolia (Chaix) Graebn.
Paronychia kapela subsp. serpyllifolia (= Paronychia serpyllifolia), commonly known als silver nailwort, is a perennial with tiny papery flowers.
Paronychia kapela subsp. serpyllifolia was already described and the name validly published by Dominique Chaix. It was not until 1919, however, that Karl Otto Robert Peter Paul Graebner reclassified it into todays valid botanical systematics.
The slow growing perennials grow to a height of approximately five centimetres and develop as mats. They are very robust and long lived.
Paronychia kapela subsp. serpyllifolia is an evergreen plant with simple leaves. The leaves are arranged alternately along the stems. The leaves are bluish green to dark green and lanceolate to ovate with entire margins. They turn reddish brown to orange in autumn and winter.
Flowers and Fruit
The tiny flowers are yellow and inconspicuous. What makes the plants decorative are the silvery white bracts that have a silky, translucent texture. The flowers are arranged in cymes and appear in May and June.
The fruits are achenes.
Paronychia kapela subsp. serpyllifolia is native to the French Pyrenees, to the French and Italian Southwest Alps, to Morocco and Algeria.
Paronychia kapela subsp. serpyllifolia prefers a sunny site and can withstand temperatures down to -17,7Âº C. It grows best in sandy-gritty soil that is dry to moderately moist.
Well suited for rockeries, dry steppes, stone gaps and mural crowns. Its low maintenance needs also make it a good plant for roof greening. The plants are shown to best advantage in groups of three to ten specimens. They should be planted at 15 to 20 centimetres of each other.
Remove brown leaves in spring.
Easily propagated by dividing in spring.
