Geranium wallichianum 'All Summer Joy' is a reliable, long-flowering hardy geranium, producing bright violet-blue flowers with pale centres continuously from early summer well into autumn. Low-growing and spreading, it forms a loose, ground-hugging mound of fresh green foliage, making it ideal for borders, ground cover, or weaving through other perennials. Fully hardy and easy to grow, it performs best in sun or partial shade.
