Latin name
Diervilla 'Firefly'
Common name
Dierville ‘Firefly’
Type
Native ornamental shrub
Family
Caprifoliaceae

Diervilla 'Firefly' is a remarkable native ornamental shrub known for its dark foliage and high tolerance to difficult conditions. It forms a compact, dense, and slightly spreading habit, perfectly suited for beds, borders, slopes, and low-maintenance naturalistic landscapes. Its deciduous foliage, a very dark, almost black brownish-purple, creates a striking contrast with its small, bright yellow flowers that appear in early summer and attract pollinators. In autumn, the foliage blazes with scarlet red and orange hues, extending its decorative appeal. Extremely hardy and very drought-resistant once established, Diervilla 'Firefly' is perfectly suited to Quebec conditions and is an excellent choice for adding color, robustness, and ecological value to the garden.
