Dianthus is a genus of flowering plants in the family Caryophyllaceae, commonly known as carnations, pinks, or sweet williams. These perennials are prized for their fragrant, colorful blooms that range from pink and red to white and purple. Dianthus plants typically have slender, green stems and narrow, grass-like leaves. They thrive in well-drained soil and full sunlight, making them ideal for garden borders, rock gardens, and container planting. Their long-lasting flowers attract pollinators like butterflies and bees, adding vibrancy and fragrance to any garden.
