More About Euphorbia ‘Blackbird’

Euphorbia ‘Blackbird’ is prized for its dramatic, near-black foliage that provides striking contrast throughout the growing season. In early spring, stems are topped with vivid chartreuse bracts that glow against the dark leaves, creating one of the most eye-catching color combinations in perennial gardens.

Unlike many euphorbias grown primarily for flowers, ‘Blackbird’ delivers season-long foliage interest. The upright, clumping habit stays tidy and architectural, making it easy to integrate into both formal and naturalistic plantings.

Why We Like It (Our Trials)

In our trials, ‘Blackbird’ has proven to be exceptionally tough and dependable. It handles heat, drought, and variable light conditions with ease, maintaining rich foliage color without burning or fading.

We especially appreciate its low-maintenance nature. Deer avoid it, pests are rarely an issue, and once established it requires very little care. It performs beautifully in mixed borders, woodland edges, and partially shaded beds where dark foliage is hard to come by.

Euphorbia ‘Blackbird’ vs. Other Euphorbia

Compared to green-leaved euphorbia varieties, ‘Blackbird’ offers far stronger foliage contrast and a more dramatic presence even outside of bloom. While traditional types rely on spring flowers for impact, this variety looks intentional year-round.

When compared to Euphorbia ‘Ascot Rainbow’, ‘Blackbird’ provides a darker, more restrained palette, trading variegation for depth and richness. For gardeners seeking a bold, low-maintenance perennial with dramatic foliage and spring interest, Euphorbia ‘Blackbird’ is an outstanding choice.
