Mexican Fleabane (Erigeron karvinskianus)
An exceptionally long-flowering and charming perennial, Mexican Fleabane is a must-have for adding a soft, frothy, and informal touch to the garden. It produces a seemingly endless succession of small, delicate daisy-like flowers from late spring right through to the autumn frosts. The blooms are magical, as each one opens pure white before gradually ageing to shades of soft pink and then purplish-rose, meaning all three colours are present on the plant at once. It has a low, trailing habit and a remarkable ability to self-seed and thrive in the tiniest cracks and crevices, softening hard edges and creating a beautiful, cottage-garden feel. It is incredibly tough, drought-tolerant, and beloved by bees and butterflies.
