Dianthus caryophyllus
flowerSpray carnations are flowering plants that produce multiple blooms per stem, creating a fuller, bushier appearance than standard carnations. These long-lasting cut flowers are prized for floral arrangements and come in a wide range of colors including pink, red, white, yellow, and bicolors. They are relatively easy to grow and perform well both in garden beds and as cut flowers for indoor enjoyment.
