Calamagrostis acutiflora 'Overdam' - Grass - Herbaceous Perennial - Height 60-70cm - 6.5lt

Calamagrostis acutiflora 'Overdam' is a striking, upright ornamental grass known for its refined appearance and architectural form. Reaching a height of about 1.2 to 1.5 meters in flower, it forms neat, vertical clumps of narrow green leaves edged with creamy-white margins. This variegated foliage brightens garden spaces from spring through autumn, providing a soft yet structured backdrop to other plants.

In early to midsummer, 'Overdam' produces tall, feathery flower plumes that emerge with a pinkish tinge before maturing to a warm golden-tan. These airy inflorescences rise well above the foliage, adding movement and height, and persist into winter, bringing seasonal interest and subtle texture even in dormant landscapes.

Unlike many grasses, 'Overdam' begins growth early in the season and remains tidy, making it ideal for formal borders, contemporary designs, or as a vertical accent in perennial beds. It performs best in full sun and well-drained soil and is tolerant of urban conditions, wind, and clay soils. Low-maintenance and deer-resistant, it only requires a spring cutback to prepare for new growth. ‘Overdam’ is a versatile, elegant choice for adding structure, brightness, and year-round appeal to gardens.
