A spidery cobweb plant!
Sempervivum arachnoideum is a species native to the mountains of Europe (Pyrenees, Corsica, the Apennines and Cantabrian Mountains). It is an orophyte (*) succulent found at altitudes of between 400 and 3000 m on rocks, scree and in cracks and crevices.
This curious plant is easy to grow and was first introduced into domestic gardens in 1699. It works well:
- in pots or troughs or as part of a green roof;
- as edging in a rock garden:
- on an old dry stone wall;
- in-between paving stones.
Accompanying plants: Sedum purpurascens, Sedum spathulifolium, Sedum spurium 'Voodoo', Artemisia caucasica, Artemisia laxa.
The Sempervivums are as undemanding of care as the Sedums. They like a warm location, sandy, neutral to alkaline soil, even if it is poor and dry. A fine gravel mulch will protect the plant from too much damp in winter and will set off the silvery rosettes to good effect.
Common name: Cobweb house-leek or Hen-and-chicks
(*) An orophyte is a plant that grows in a subalpine habitat.
(**) araneous: extremely thin and delicate, like a cobweb.
