Miscanthus sinensis 'Undine'

Miscanthus sinensis 'Undine'



About this cultivar:

Miscanthus sinensis 'Undine' has the Royal Horticultural Society Award of Garden Merit (RHS AGM). The 2004 trial notes say 'Leaves with white midrib turn orange and straw coloured in autumn. The arching red inflorescences turn rose/buff when mature. Tall, airy, fine and graceful. Particularly good for winter foliage impact.' Who are we to disagree with the very Royal very Horticultural Society !?!?!

I believe an introduction from Ernst Johann Friedrich Pagels (1913- 2007), who was a German gardener and plant breeder. After Karl Foerster, his role model, and Georg Arends, Pagels became the most important German breeder of the 20th century. In total, he introduced more than 130 varieties in the course of almost 50 years of breeding work. His speciality was Miscanthus and other genus that have went on to become popular in the New Perennial movement, especially in Great Britain and the United States.

About this genus:

Miscanthus gets it name from the Greek for stem, miskos, and flower, anthos. It is commonly known as Maiden Grass. It is renowned for its versatility as a tall, perennial, ornamental grass. New introductions from Germany and Japan have improved stature, foliage colour, and flower heads.

Many of the popular hybrid Miscanthus are variegated (e.g., Miscanthus 'Morning Light') and many Maiden grasses also have attractive seed heads. Variegated ornamental grasses offer a colour contrast in the garden as well as a pleasing habit.

A few selections of Miscanthus sinensis are controversial because they re-seed excessively, primarily in disturbed sites. We continually discard any Miscanthus that displays this tendency.

Try pairing Miscanthus with flowering plants such as Helianthus, Echinacea, Coreopsis or Sedum. Mainden Grass also looks great in large drifts where the leaves and flower heads can be seen swaying in the wind. It is a tough, low maintenance plant which makes it perfect for wet or dry gardens in any situation apart from full shade. Miscanthus is versatile from a design standpoint; it can be used as a specimen, for massing or screening, in large containers, or at the pond's edge. I say plant this grass where its wonderful winter interest can be enjoyed!
