Geranium oxonianum 'Thurstonianum' - 2026

Geranium × oxonianum 'Thurstonianum' is a hardy, perennial plant celebrated for its vibrant violet-blue flowers that bloom from late spring to early summer, forming a long-lasting and abundant display. The saucer-shaped blooms are carried above finely divided, bright green foliage that forms a dense, spreading mound, adding structure, texture, and visual interest to borders, rockeries, or naturalistic plantings. Its flowers attract pollinators such as bees and butterflies, supporting garden biodiversity while enhancing the ornamental appeal of the planting.

Thriving in full sun to partial shade with well-drained soil, Geranium × oxonianum 'Thurstonianum' is hardy, low-maintenance, and adaptable to a range of soil types. Occasional cutting back of spent flowers encourages fresh foliage and can extend the flowering period. Its combination of abundant, long-lasting blooms, lush foliage, and pollinator-friendly attributes makes it a reliable and versatile choice for cottage gardens, mixed borders, and naturalistic plantings.
