Pyrethrum, fam. Asteraceae.
   Occurs in garden beds. During some time in spring, the leaves of pyrethrum, looking like parsley, can confuse someone at first. Only in June it turns out that this is a flower similar to small daisy, and not from Apiaceae (Celery) family, as might be supposed. The flowers aroma is a little pungent. Along with typical white-flowered species, there are also colored, for example with pink petals.
   The name is derived from Greek word "pyretos" – "fever", given for ability of some varieties to decrease temperature at illness. Pyrethrum is used against helminths, ticks and insect pests (fleas, bedbugs, gnats, mosquitoes and cockroaches).
