Pyrethrum

   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).
