Scentless chamomile is an annual, biennial or short-lived perennial. The stems are erect, hairless and branch 20 - 74 cm high. The leaves alternate and are finely dissected. Flowers are borne at the end of the branched stem. They are white with yellow centres with numerous flowers on each plant. Seeds are dark brown and grooved and possess some dormancy. The plant germinates readily in the spring and fall. It has a dense fibrous root system which spreads rapidly during wet periods.
Frequent shallow tillage in fall and spring will help in the destruction of seedlings. A cultivator with mounted harrows has been the most effective in killing the seedlings. If the soil is wet, many plants will re-establish.
Seeding to bromegrass for several years will reduce the infestation.
Mowing must be done early to prevent seed production and at least two mowings would be necessary in most years.
