Trachymene coerulea, commonly known as Didiscus caeruleus or Blue Lace Flower, is a delicate annual native to Western Australia, celebrated for its soft, lacy clusters of pastel-blue to lavender blossoms. Belonging to the carrot family (Apiaceae), this graceful plant typically grows 18 to 30 inches (45 to 75 cm) tall, with slender, branching stems and finely divided, fern-like foliage that enhances its airy appearance. From summer through early autumn, it produces dome-shaped umbels composed of dozens of tiny star-like flowers, each radiating a gentle fragrance that attracts bees, butterflies, and other pollinators. The blossoms have a charming, old-fashioned quality and are prized in floral arrangements for their romantic color and texture, often used fresh or dried. Trachymene coerulea thrives in full sun and well-drained soil, tolerating light drought once established, and performs best in moderate climates. Its elegant form and soft hues make it ideal for cottage gardens, wildflower borders, and mixed plantings, where it adds a light, graceful touch and a soothing blue accent among brighter blooms.
