Heuchera ‘Cassis’ is an evergreen perennial admired for its deep, rich purple foliage that forms neat, rounded clumps. In late spring to early summer, delicate sprays of small, bell-shaped flowers rise above the foliage, adding subtle seasonal interest and a light, airy texture. Its bold leaf colour and compact habit make it ideal for borders, rockeries, woodland gardens, or container plantings.

Thriving in partial shade to full sun with moist, well-drained soil, ‘Cassis’ is hardy and low-maintenance. The ornamental foliage provides year-round appeal, while the seasonal flowers attract pollinators, enhancing garden biodiversity. Its combination of striking leaf colour, reliable growth, and seasonal blooms makes it a versatile and attractive choice for adding structure, texture, and visual impact to a variety of garden settings.
