Plant Highlights: Cream-variegated foliage • Upright architectural habit • Elegant feathery flower plumes • Long season of interest • Excellent for borders and containers
Overview
Calamagrostis × acutiflora 'Overdam', commonly known as Feather Reed Grass, is a striking ornamental grass valued for its upright habit and attractive cream-striped foliage. Neat clumps of arching green leaves edged with creamy white provide structure from spring onwards, while tall, feathery flower plumes rise above the foliage in summer, gradually ageing to warm golden tones that remain attractive well into winter.
Its strong vertical form makes 'Overdam' an excellent choice for adding height and movement to mixed borders, prairie-style planting and contemporary gardens. The compact, clump-forming habit also makes it suitable for large containers where its elegant silhouette can be appreciated throughout the seasons.

Growing Guide
Position
Plant in full sun for the strongest upright growth and best flowering, although it will also perform well in partial shade. It is ideal for open borders where its vertical habit can be fully appreciated.
Watering
Water regularly during the first growing season while establishing. Once established, plants tolerate short dry spells but perform best with evenly moist soil during active growth.
Soil
Grow in fertile, well-drained soil enriched with organic matter. It adapts to a range of soil types provided they do not remain permanently waterlogged.
Hardiness and Winter Care
Fully hardy in Irish gardens. Leave the faded flower heads and foliage standing through winter for seasonal interest and wildlife value, then cut the plant back to around 10–15cm above ground level in late winter or early spring before new growth begins.
Routine Care
Requires very little maintenance. Divide mature clumps every few years in spring if they become congested, helping to maintain vigour and flowering performance.
Perfect For
- Mixed herbaceous borders.
- Prairie and naturalistic planting.
- Contemporary gardens.
- Large patio containers.
- Creating vertical structure and movement.
Good to Know
Unlike many ornamental grasses, Calamagrostis × acutiflora 'Overdam' maintains a strong, upright habit throughout the growing season and rarely flops, even after summer rain, making it one of the most reliable architectural grasses for Irish gardens.
