Pennisetum alopecuroides 'Weserbergland' 'Weserbergland' Fountain Grass1

Edward F. Gilman2

Introduction

'Weserbergland' is a dwarf cultivar of fountain grass that often reaches 3 feet tall and wide (Fig. 1). It grows slightly larger than 'Hameln'. The white inflorescence resembles a bottle brush and persists into fall. These attractive, 5- to 7-inch-long flowers persist on the plant from summer to fall but shatter in the early winter. The foliage of fountain grass is bright green during the summer, but turns to a golden brown color in the fall after the flowers begin to die. The foliage arches near the tip and gives the plant a graceful fountain shape. Fountain grass is an outstanding, elegant, fine-textured ornamental grass.

Use and Management

This graceful plant has a beautiful effect when its image is reflected in water. It is usually massed together in a landscape bed or planted in a perennial border to provide fine texture. It is suited for the residential landscape more than most other ornamental grasses because of its small size. It can "make" a landscape with its extremely fine texture that provides a cooling effect as it blows in even the slightest breeze. Fountain grass makes an effective, tall ground cover plant or single specimen plant.

Fountain grass needs to be planted in a site that receives full sun and has well-drained soils. Be prepared to provide some irrigation during dry weather in the summer. The center of the plant becomes open as the plant ages with most of the stems originating along the margin of an open ring. Divide the open clump and re-plant to rejuvenate it.

The propagation of this grass is by division every 5 to 10 years.
