Sunflor Series dianthus are hardy, floriferous hybrids that bloom in a wide array of colors, some with fragrant blossoms. Their neat clumps of green to gray-green, waxy, strap-like leaves are topped with large, single or double flowers from late spring through summer. The blooms are held on short, sturdy stems and appear in a range of solids and bicolors. A terrific choice for containers, rock gardens or sunny mixed borders.
