Yellow Ageratum, also known as Golden Ageratum, is a hardy, adaptable Mediterranean-native that blooms all summer with dense clusters of bright yellow, button-like flowers. Its extended bloom period makes it ideal for borders, cutting gardens, or tucking it in between perennials in mixed garden beds. Thriving in full sun and well-drained soil, it's a butterfly magnet and an excellent choice for both fresh and dried floral arrangements.
