HEUCHERA BLACK PEARL

Description and Characteristics

Heuchera ‘Black Pearl’ is a stunning, award-winning evergreen perennial known for its glossy, jet-black foliage and compact, tidy form. One of the darkest Heucheras available, ‘Black Pearl’ makes a dramatic impact in borders, containers, and shaded garden beds, where its unique colour provides bold contrast all year round.

The plant forms a dense, rounded mound of large, deeply lobed leaves with a ruffled edge. The foliage emerges a rich, dark burgundy-black and quickly matures to a near-black sheen with subtle maroon undersides. This variety is known for maintaining its colour in heat and humidity and for its ability to stand out in both sun and shade.

In mid to late summer, ‘Black Pearl’ produces slender, dark flower stems bearing small, soft pink to white bell-shaped flowers that rise above the foliage. While the flowers are attractive and pollinator-friendly, the foliage remains the star feature.

‘Black Pearl’ grows to approximately 20–25 cm tall and 30–40 cm wide, with flower spikes reaching up to 40–50 cm. It’s ideal for edging, containers, underplanting, and shade gardens.
