Many of these have achieved the renowned RHS Award of Garden merit, where their independent trials and assessments over many years to sift out the winners. We try and offer something a little different too - new colours, and new varieties, as well as proven winners and ever-popular types. We sell both potted perennial plants in 9cm pots and plugs, both of which are suitable for planting straight into the garden Spring, Summer or Autumn. The 9cm pots will quickly establish and flower in your garden.
