Bidens ferulifolia is a low-maintenance, sun-loving annual that bursts with vibrant yellow flowers from summer to early autumn. Known for its finely divided, fern-like foliage and profuse flowering habit, Bidens adds a sunny splash of colour to any Irish garden, patio pots, hanging baskets, or borders.

Thriving in full sun and well-drained soil, Bidens tolerates the mild, often wet Irish summers and continues blooming reliably despite variable weather. It’s a magnet for bees and butterflies, supporting local pollinators while brightening your outdoor space.
