Outstanding Qualities

Ageratina altissima ‘Chocolate’ (formerly Eupatorium rugosum ‘Chocolate’) is a medium-sized perennial with attractive bronzy-chocolate foliage and late-blooming white flowers. The deep purple foliage is great as a backdrop for smaller perennials and mixes well in the garden with other plants. The white flowers open very late in the season, often not until late September or early October.
