Description
Scentless mayweed (Tripleurospermum inodorum), also known as sea mayweed, dog gowan, and scentless false chamomile, is a hardy annual wildflower commonly found across the UK. It grows naturally in coastal areas, arable land, and waste ground, often thriving in sand, gravel, and amongst beach pebbles.
Despite its resemblance to scentless chamomile, this plant has no noticeable scent, which is how it gets its common name. It is a tough, adaptable species that can tolerate poor soils and exposed locations.
How to Identify
This upright bushy annual produces familiar daisy-like flowers with white ray florets surrounding a bright yellow centre. Each flower head is made up of tiny yellow disc florets and is held above finely divided, feathery foliage.
Plants are typically well-branched and carry multiple blooms throughout the summer months. Key identifying features include the green involucral bracts beneath the flower heads and the absence of any chamomile fragrance.
How to Grow
Scentless mayweed grows best in full sun and adapts easily to most soil types, particularly well-drained or poorer ground. It is ideal for wildlife-friendly areas, wildflower meadows, and informal garden spaces.
Seeds can be sown directly outdoors in spring or autumn, where they will establish quickly with minimal care. The flowers are highly attractive to a wide range of insect species, providing nectar and pollen for pollinating insects, while the leaves, stems, and developing seed heads support insect larvae.
