Flowering Plant


Sweet William (Dianthus barbatus) is a classic garden favorite known for its clusters of vivid blooms in mixed colors. Sweet William thrives in full sun to partial shade with well-drained soil, making it great for borders, cottage gardens, and cut flower planting. Its flowers often attract pollinators, and deadheading encourages prolonged blooming. While technically a biennial, many gardeners grow it as an annual or allow it to self-seed.
