dianthus & roses
We're re-doing our center bed and I finally have decided on the plants and layout. It is a circular bed with 4- 12x12 stepping stones in the center w/ a sundial on pedestal and more stepping stones bisecting the circle like an "X" (it is 10' across). In pots at the center of the circle in ea. of the 4 quadrants I am putting plumbago. In front of that I want a rose in each section (was thinking KO Rose??? other suggestions for 3-4' high or less everbloomer w/ scent?) In front of the roses is thyme (4 different varieties, one in each quadrant), all along the outer edge is heather and lining the stepping stones I want borders of dianthus.
What are the best evergreen varieties of dianthus that have LONG bloom times?? Perennial in Z7. Thanks!
