I Love this dianthus. This variety should have won perennial plant of the year instead of Firewitch. I like Firewitch also, but Greystone has spread triple the width of Firewitch, in my garden, to around 4 feet. It has a nice neat habit, easy to grow, the deer haven't touched it, and the pure white color goes with everything.

Short 8-12" - plant 2' apart. zone 3-9. Plants spread up to 4 feet wide with white, fringed, fragrant flowers. Heat tolerant, fragrant and long blooming. Easy to grow, easy to maintain, lots of flowers.

Editor's Comment:

While this might be this person's experience, most of the Dianthus gratianopolitanus cultivars should be spaced 6-12" apart, not 2'. According to Plant Delights Nursery, this particular Dianthus will spread and make a tight mound to 4' wide.
