Clusterhead Pinks is a Dianthus oddity hailing from the alpine regions of central and southeastern Europe.  Like all Dianthus, D. carthusianorum prefers soil with sharp drainage but the brilliant pink flowers of this gem stand 2-3 feet above the foliage, not unlike one of our favorites Verbena bonariensis. Equally at home in a prairie or rock garden, this exciting Dianthus species deserves much more attention that it currently gets in the trade.  It probably owes its name to the Catholic order of the Carthusians, who cultivated it early on in their monastery gardens and as medicinal plant.
