Black Beauty Fountain Ornamental Grasses Description


Black Beauty Fountain Grass is a distinctive ornamental grass valued for its deep purple-black foliage and elegant, arching growth habit. It forms a compact, rounded clump, typically reaching around 60 cm (2 feet) in height and spread, making it an excellent choice for smaller gardens, borders and containers.

Its dark, glossy foliage creates a bold contrast against green plants and colourful flowers. In late summer, feathery, bottlebrush-like flower spikes emerge in rich purple shades before gradually fading to soft silvery tones as they mature. This combination of dark foliage and delicate flowers creates an eye-catching display that extends into autumn.

With its compact size and attractive seasonal features, Black Beauty Fountain Grass is a versatile choice for adding colour, texture and movement to a range of garden styles.

Pruning Advice


When to Prune: The best time to prune Black Beauty Fountain Grass is in late winter or early spring, just before new growth begins. This removes the previous season's foliage and creates space for fresh shoots to emerge.

How to Prune: Use clean, sharp secateurs or garden shears to cut the previous season's growth back to approximately 10 to 15 cm (4 to 6 inches) above ground level. Remove dead or damaged foliage carefully to encourage healthy new growth.

Additional Care: Black Beauty Fountain Grass generally requires minimal maintenance beyond annual pruning. If the plant becomes overcrowded or its centre begins to die back, consider dividing it in early spring to rejuvenate the clump. During the growing season, remove any damaged or untidy leaves to maintain its appearance.

Further Information


Striking Foliage: Black Beauty Fountain Grass is prized for its dramatic purple-black foliage, which creates a bold contrast when planted alongside lighter foliage, ornamental grasses or flowering perennials.

Seasonal Interest: Its graceful, bottlebrush-like flower spikes emerge in rich purple shades in late summer and gradually fade to silvery tones as they mature. Combined with its dark foliage, these flowers provide attractive colour, texture and movement through autumn.

Low Maintenance: Once established, Black Beauty Fountain Grass is relatively easy to care for. It can tolerate periods of dry weather and grows in a range of soil types, provided drainage is suitable. Annual pruning helps keep the plant tidy and encourages fresh growth.

Pollinator Friendly: The flowers may attract visiting pollinators, including bees and butterflies, adding further interest to wildlife-friendly planting schemes.

Versatility: With its compact size and distinctive foliage, Black Beauty Fountain Grass works well in garden borders, containers and mixed planting schemes. It can also suit some coastal gardens where local growing conditions are appropriate.
