Tansy

Common Name:
Tansy

Description:
Tansy is a hardy, herbaceous perennial valued for its vibrant clusters of bright golden-yellow button-like flowers and finely divided, aromatic foliage. Blooming prolifically through summer, it creates a striking display that adds bold colour and texture to garden beds and borders. Traditionally known for its natural insect-repelling properties, Tansy emits a strong scent that can help deter pests, making it a practical addition to productive and ornamental gardens alike. Well-suited to Melbourne conditions, it thrives in full sun and adapts to a range of soil types, provided they are well-drained. Once established, it is drought tolerant and requires minimal maintenance, though regular pruning will help control its vigorous growth. Tansy can spread readily via underground rhizomes, forming dense clumps, and is best managed in contained areas or where its spreading habit can be appreciated.
