Growing Sempervivum in a vertical garden

As its Latin name suggests – ‘always living’ – this is a hardy succulent. Sempervivum
is an alpine succulent, used to eking out a living between rocks and crevices. It takes a
black thumb to knock one of these about. Sempervivum will happily squish into a
vertical planter. Each rosette is a separate plant, and is monocarpic – it will die after it
flowers – but is quickly replaced by new rosettes. They look good combined with
echeveria as well.
