Sempervivum Red Ace

Well named - very red and top of the pack. When growths re-starts in spring the rosettes start to swell and colour up until they are almost scarlet. Each leaf is edged and tipped with silvery hairs which only enhances the effect.

However, it is quite a soft grower and will benefit from a bit of protection in wetter areas - even keeping the worst of the rain off will help, or grow it in a terracotta pot and move it somewhere drier for winter. Worth the effort.
