Late last spring, something stopped me in my tracks as I was walking in the garden. It was an indescribably sweet and powerful scent. I tracked the scent to Dianthus ‘Greystone,’ which I planted two years ago. I thought, if all Dianthus smell this amazing, then I needed to plant more! And so last year I did indeed plant several more cultivars. I doubt, however, that any of them will be as floriferous as Greystone.
The grass-like foliage is a pretty bluish green, and is dense and evergreen, making an excellent weed smothering groundcover. Although Bluestone Perennials says that it grows to 4 feet wide, mine hasn’t spread too much, and it hasn’t bullied its neighbors. Last year it bloomed from May 26 to June 18.
Note: I just checked on my plant of Dianthus ‘Greystone,’ and strangely, the foliage died back this winter, leaving a loosely matted mess. Little shoots are coming out of the old foliage though, so I’ll wait and see before I cut anything back.
