Pyrethrum, << py REE thruhm or py REHTH ruhm, >> is a type of flower. Pyrethrums are also called painted ladies or painted daisies. The flower heads of pyrethrums grow singly or in clusters on erect stems that rise 1 foot (30 centimeters) or more. Pyrethrum flowers look like daisies with pink, white, crimson, or lilac rays. Pyrethrums bloom in spring or early summer. They are grown as garden flowers or for cutting.
An insecticide is made from the dried and powdered flowers of certain pyrethrums. This insecticide is also known as pyrethrum. It is one of the least poisonous insecticides to animals and people. It is used in liquids, powders, and sprays for insect control on animals, in the garden, and in the home.
A pyrethrum known as feverfew is a traditional treatment for mild fever. A sedative traditionally used to treat pain is also called pyrethrum. But it is made from the root of a different kind of plant.
