The Dianthus ‘Ruby’s Tuesday’ has flowers that are a deep red carnation with a sweet fragrance. Their very compact habit and free blooming nature make it a stand out both in container gardens and perennial borders. These will bloom from mid summer to early fall. Dianthus needs a sunny site with well-drained soil, but will tolerate some shade in the afternoon and humidity. These fragrant, spicy dove like flowers look wonderful as a border plant, great for rock gardens, or along walks or paths. Zones 4 to 11.
