What is that white flower, looking stunning (ever slightly floppy) behind my 'Matrona' sedum? Oh, just some agapanthus. Why yes, I DO live in zone 5. Hmm? Oh, yes, agapanthus are generally only hardy to zone 7, at best. Do I bring it inside for the winter? No, this is a hardy version! You didn't know zone 5 hardy agapanthus existed? Well, neither did I until I saw it in the Arrowhead alpines catalog.
