Sempervivum 'Casablanca' is strikingly beautiful. The rich dark tips of this sempervivum have strong visual impact, so it will stand out in your collection. Bred by Martin Haberer (Germany) in 2008. Winner of Sempervivum of the Year 2021. Indistinguishable from 'Adamina', which we have also previously grown (so if you've got it, you probably don't want both).
