    Named after the well known grass expert Poul Petersen of Overdam nursery in Denmark, this relatively new variety forms good sized clumps of quite upright stems. It looks superb in prairie style planting mixed with summer flowering perennials such as Echinaceas or Achilleas, but it also has a strong enough presence to be used in gravel gardens. They are perfect for adding movement too as their delicate flower spikelets will waft happily in the lightest breeze.

  • Garden care: Cut back in early spring before the new foliage appears

      It is difficult to be too specific about growth rates as this is largely determined by things like the soil type and available water, light and nutrients. As a very general guide then and given reasonable conditions, I would say that it will probably take around 5 - 7 years for the grasses to reach their full spread. Planting distance then, will be determined by how impatient you are. If you want more immediate impact, you could plant 5 per square metre, 3 per square metre if you want to compromise, or 1 per square metre if you are planting for the long term.

Shimmering late-season grasses

With the garden devoid of summer froth and carpeted in autumn leaves, certain plants shine at this time of year, a well-placed grass shimmering against a winter sunset, or the reddish brown, silky feathers shimmering in low sunlight are winter treats.
