Geranium wallichianum 'Sylvia's Surprise' is a striking and distinctive hardy geranium, producing vivid pink flowers dramatically marked with white central splashes, creating a bold, eye-catching effect from early summer into autumn. Low-growing and spreading, it forms a loose mound of fresh green foliage, making it ideal for borders, ground cover, or weaving through other perennials. Fully hardy and easy to grow, it thrives in sun or partial shade.
