    About Pennisetum setaceum

    Pennisetum setaceum, commonly known as Fountain Grass, is a clumping ornamental grass valued for its graceful arching fountain-like form and feathery pinkish flower spikes that sway in the lightest breeze. The fine narrow foliage forms dense rounded tussocks that bring movement, texture and a sense of softness to architectural and contemporary plantings.

    It performs best in full sun with free-draining soil and is highly drought tolerant, heat tolerant and low maintenance once established. Pennisetum setaceum thrives across a wide range of conditions including coastal exposure, poor soils and reflective heat, and is well suited to mass plantings, accent groupings, modern borders and large containers.

    As a textural feature in contemporary, coastal and Mediterranean-style gardens, in mass plantings, mixed borders, raised beds and large pots, Pennisetum setaceum brings architectural softness, seasonal flower interest and a low-maintenance reliability that pairs beautifully with structured planting and hard landscaping.

    Frequently Asked Questions

    About Pennisetum setaceum Fountain Grass

    How tall does Pennisetum setaceum grow?

    Pennisetum setaceum generally reaches around 60 to 90 centimetres tall and 60 to 90 centimetres wide, with flower spikes lifting to around 1 to 1.2 metres at peak. The arching fountain form gives the plant a soft graceful silhouette.

    When does Pennisetum setaceum flower?

    Pennisetum setaceum produces feathery pinkish flower spikes from summer through autumn, rising above the foliage and catching the light beautifully. The flower spikes hold well and can be left on the plant through winter for ongoing texture and movement.

    Where should I plant Pennisetum setaceum?

    Pennisetum setaceum grows best in full sun with free-draining soil. It suits contemporary borders, coastal gardens, mass plantings, accent groupings, raised beds, gravel gardens and large containers, tolerating coastal exposure, poor soils and reflective heat from paving exceptionally well.

    Is Pennisetum setaceum drought tolerant?

    Yes. Once established, Pennisetum setaceum is highly drought tolerant and performs reliably through warm, dry periods with minimal watering. Through establishment it benefits from light, regular watering, then transitions to deep, occasional watering through extended dry periods.

    Is Pennisetum setaceum frost tolerant?

    Pennisetum setaceum handles light frost once established. In colder districts the foliage may die back through winter but typically reshoots from the base in spring. A hard prune at the end of winter helps refresh the clump for the new season.

    How do I maintain Pennisetum setaceum?

    Maintain Pennisetum setaceum with an annual hard prune at the end of winter, cutting the clump back to around 10 to 15 centimetres above ground level. Fresh foliage will emerge through spring. Lift and divide clumps every three to four years if they become congested.

    How should Pennisetum setaceum be spaced in mass planting?

    For a continuous flowing mass, space Pennisetum setaceum around 50 to 70 centimetres apart. For accent groupings or feature plantings, allow 70 to 90 centimetres between clumps so each plant can develop its full arching fountain form.
