- Scentless chamomile displays white, daisy-like flowers with a yellow center. It has fernlike, finely divided leaves that are odorless when crushed.
- The plant can produce up to 500 seeds per flower head and ~300,000 seeds per plant.
- Pull and bag flower heads (don’t leave them on the ground). Don’t mow/deadhead—it leaves roots and can stimulate more flowers.
Scentless chamomile is an annual, biennial, or short-lived perennial forb.
Seedlings emerge in spring and can produce dense mat, outcompeting other species.
Each flower head can produce 500 seeds and a single plant can produce 300,000 seeds.
Flowers are white in color, ¾”, and are daisy-like flowers that are solitary on each stem. Flowers have yellow central disk surrounded by white petals. Leaves are alternate, fernlike, finely divided, and odorless when crushed. Stems can reach 6″-3′ tall and have numerous branches.
Pull, bag, and dispose of flowers. Seeds could mature and germinate if left on the ground.
Mowing, chopping, and deadheading leaves roots behind, stimulates more flower production, and are not recommended methods.
