About Pyrethrum
Tanacetum cinerariifolium, also known as Pyrethrum or Dalmatian Daisy, is a perennial herbaceous plant from the Asteraceae family, valued for its natural insecticidal properties. It features finely divided, grayish-green leaves and produces small, daisy-like white flowers on slender stems. It's ideal for low-maintenance gardens, borders, or as a companion plant to protect other crops.

Care tips
It thrives in full sun for optimal flowering and healthy development. It requires well-drained, sandy or slightly loamy soil, and is quite drought-tolerant once established, so watering should be moderate, allowing the substrate to dry out between waterings. A common mistake is overwatering, which can lead to root rot. It is cold-hardy, but will appreciate a layer of mulch in very severe winters.
