spring is on the way perhaps

We have been growing herbs, perennials and alpine plants in Montgomeryshire – Powys Paradwys Cymru – since 1988.

We cultivate a variety of herbaceous perennials, most of . which prefer a reasonably sunny and well-drained position.

Plants are usually available in 9cm and one litre pots, and are grown in sustainable compost with controlled release fertiliser.

Potting Bench – unusually tidy…


We are members of the National Botanic Garden of Wales’s assurance scheme, plants labelled with the pollinator logo are:

  • proven to support pollinators by the Botanic Garden’s research scientists
  • grown without the use of synthetic insecticides and peat compost
