St. Martin’s Buttercup (Ranunculus marginatus) bears bright yellow flowers, typically around 1.5 to 2 cm in diameter. Each flower has five glossy, overlapping petals with a slightly notched tip and a faint silvery sheen on the reverse. The centre of the flower contains numerous yellow stamens surrounding greenish carpels. It flowers from early spring to late spring, often earlier than many other buttercups, particularly in Mediterranean or southern European habitats. The blooms are held singly on upright, slender stems and are a favourite early nectar source for insects.
Fruit:
The fruit of Ranunculus marginatus forms a dense, spherical cluster of small, dry achenes—each containing a single seed. These achenes have a smooth texture and a short hooked beak at the tip, which may aid in limited dispersal. As the plant matures, the seed heads dry out and turn brown, gradually releasing the seeds into the surrounding soil. This allows the species to regenerate in suitable open habitats, especially after soil disturbance.
Leaves:
This buttercup's leaves are one of its most distinguishing features. The basal leaves are deeply lobed or divided, with broad, toothed segments that are often wedge-shaped or fan-like. These lower leaves grow on long stalks and form a loose rosette. Upper stem leaves are smaller, more finely divided, and may appear almost thread-like in comparison. The foliage is grey-green and often slightly hairy, with prominent margins—reflected in the species name marginatus, meaning "with margins".
Fragrance:
St. Martin’s Buttercup does not produce a noticeable fragrance for humans. While its vibrant yellow flowers attract early-season pollinators visually, they do not rely on scent to do so. If any scent is present, it is extremely mild and likely undetectable to the human nose. Instead, its pollination strategy relies more on colour and flower structure than on olfactory cues.
Other Names:
Lesser Celery-leaved Buttercup, Lesser Water-plantain Buttercup, Margined Buttercup.
Frequency (UK):
Rarely seen
