A great perennial for shady locations, 'Guacamole' has bright lime-green foliage that brightens up the shaded garden or mixed container. Creamy white flowers bloom above the compact foliage in spring, attracting butterflies and hummingbirds to the garden.  Prefers consistently moist soil. Great planted in masses, will contrast beautifully with dark foliage plants such as Bugbane or False Spirea.
