Proven Winners® Boom Chocolatta Cranesbill Geranium (Geranium pratense)

Proven Winners® Boom Chocolatta Cranesbill Geranium (Geranium pratense) is a striking perennial known for its deep purple flowers and unique dark chocolate-toned foliage. This bold contrast between flower and foliage creates a dramatic effect in sunny borders and mixed perennial plantings.

Blooming in early to mid-summer, Boom Chocolatta produces large, vibrant blooms that attract pollinators such as bees and butterflies. The foliage emerges with rich bronze tones and deepens throughout the season, providing long-lasting visual interest even after flowering.

This geranium forms a full, upright clump that works well in borders, mass plantings, and naturalized landscapes. It thrives in full sun to partial shade and prefers well-drained soil. In Alberta, it performs reliably as a hardy perennial, tolerating cold winters and returning each season with strong growth.
