Pyrethrum Chrysanthemum cinerariifolium

Common Name:
Pyrethrum

Description:
Pyrethrum is a charming and highly functional herbaceous perennial, best known for its daisy-like flowers and natural insect-repelling properties. It produces masses of crisp white petals surrounding bright yellow centres, creating a classic cottage garden look from late spring through to summer. Beyond its ornamental appeal, Pyrethrum is widely valued as a natural source of pyrethrins, compounds traditionally used in organic pest control, making it a practical addition to vegetable and herb gardens. The plant forms a neat, bushy clump of soft green foliage and performs well in Melbourne’s climate, preferring full sun to part shade and well-drained soil. It is relatively low maintenance and benefits from regular deadheading to encourage prolonged flowering and maintain a tidy appearance.
