Diervilla 'Firefly Nightglow' is a remarkable ornamental native shrub, noted for its very dark, almost black foliage and its excellent performance in challenging conditions. It forms a compact, dense, and slightly spreading habit, ideal for borders, embankments, and low-maintenance naturalistic plantings. Its deep black-purple deciduous foliage spectacularly highlights its summer bloom, which consists of small, nectar-rich, bright yellow flowers that are very attractive to pollinators. In the fall, the foliage ignites with intense scarlet red and orange hues, extending its decorative appeal until the end of the season. Extremely hardy and very drought-tolerant, Diervilla 'Firefly Nightglow' is perfectly suited to Quebec's conditions and is a sustainable choice for adding contrast, color, and ecological value to the garden.
