Why we love this plant!

A standout in pollinator-friendly gardens, this herbaceous perennial produces striking white or pale lavender flower spikes with delicate filaments resembling cat’s whiskers. Well-suited to South East Queensland’s warm climate, it thrives in garden beds or containers, attracting bees and butterflies throughout the flowering season. Often used in traditional medicine, it has additional cultural significance. Its ability to flourish in a range of conditions makes it a great choice for informal borders, native gardens, or as a feature plant in wildlife-friendly landscapes.
