Sempervivums & Sedums

Sempervivums and sedums can be quite cold tolerant.  Both my sempervivum collection and my Sedum dasyphyllum 'Major' are spending almost every day outdoors.  The sempervivum winter coloration is especially compelling; the Sedum dasyphyllum 'Major' is a more attractive plant in its fresh juvenile form but it has an oddly compelling noodle-like appearance as it ages and winterizes.
