About

Anacyclus pyrethrum, the pellitory, Spanish chamomile, Mount Atlas daisy, bertram, or Akarkara, is a species of flowering plant in the daisy family Asteraceae. It is native to Mediterranean Europe and parts of North Africa, but also naturalised in other parts of Europe, India and Pakistan. This herbaceous perennial resembles chamomile species in habitat and appearance.

The plants known as pellitory-of-the-wall and spreading pellitory belong to a different family, the nettles (Urticaceae).

How to grow it

Anacyclus pyrethrum var. depressus (sometimes considered a separate species, Anacyclus depressus), called mat daisy or Mount Atlas daisy, is grown as a spring-blooming, low-water ornamental. It produces mats of grey-green, ferny foliage and single daisy-like white flowers. It is suitable for growing in an alpine or rock garden. It has gained the Royal Horticultural Society's Award of Garden Merit.

Uses

Extracts of Anacyclus pyrethrum have anabolic activity in mice and also increase testosterone in the animal model.
