Calamagrostis Overdam 2 Litre Pot

Calamagrostis × acutiflora ‘Overdam’ – A Striking, Variegated Grass with Elegant Form and Year-Round Interest

Calamagrostis × acutiflora ‘Overdam’ is a refined, cool-season ornamental grass that brings graceful structure, movement, and subtle colour to the garden. With its upright habit and creamy-white variegated foliage, ‘Overdam’ adds light and texture to borders from early spring through winter. This elegant feather reed grass offers a long season of interest, from its crisp, striped blades in spring to the tall, feathery plumes that emerge in summer and persist beautifully into the colder months. Perfect for modern, naturalistic, or formal planting schemes, it’s a low-maintenance, stylish solution for adding height and contrast without overwhelming surrounding plants.

Why Grow Calamagrostis ‘Overdam’?

Elegant Variegated Foliage – The finely textured leaves are edged in creamy white, providing a soft, luminous effect that brightens borders and blends effortlessly with other perennials and grasses.

Graceful, Upright Habit – With a strong vertical form, ‘Overdam’ stands tall and narrow, bringing structure to mixed plantings without spreading aggressively or flopping, even in heavy rain.

Feathery Summer Plumes – In early to midsummer, silvery-pink flower spikes rise above the foliage, gradually maturing to a warm golden-tan. These airy plumes remain standing through winter, catching the light and adding seasonal interest.

Low-Maintenance & Drought Tolerant – Once established, this grass is remarkably resilient and requires very little care. It’s well-suited to a wide range of soil types and is especially useful in urban or low-water landscapes.

Versatile & Stylish – Whether in a minimalist modern garden, a naturalistic prairie-style scheme, or a traditional mixed border, ‘Overdam’ contributes structure, movement, and a refined colour palette.

Planting & Care Guide

Position: Thrives in full sun to light shade. While it tolerates some shade, the best leaf colour and upright habit are achieved in sunny spots.

Soil: Prefers well-drained soil but adapts to a variety of conditions, including clay and loam. It performs best in moderately fertile soil with good drainage.

Watering: Water regularly after planting to establish strong roots. Once mature, it handles dry periods well but benefits from occasional deep watering in prolonged drought.

Maintenance:

• Cut back to the base in late winter or early spring before new shoots appear.

• Divide clumps every few years in spring to refresh growth and maintain a tidy shape.

• Leave flower heads standing through winter for architectural interest and wildlife value.

Perfect Plant Combinations

Calamagrostis ‘Overdam’ pairs beautifully with perennials like Echinacea, Salvia, and Sedum, where its soft foliage and upright plumes contrast with bold flower forms. In modern plantings, combine it with Allium, Nepeta, or Achillea for a breezy, textural effect. Its luminous foliage also makes it an ideal partner to darker-leaved plants such as Heuchera or Persicaria, creating striking visual contrast. For winter interest, plant alongside evergreens or structural shrubs like Cornus or Buxus to extend the garden’s appeal year-round.
