    Much admired at the RHS Garden Wisley, this border will create a colourful, summer-long display. These beautiful perennials will all thrive side by side in a sunny bed with moist but well-drained soil.

    Our Wisley border collection contains 15 plants, 3 of each of Echinacea, Saponaria, Eryngium, Persicaria, and Phlox.

  • 3 x Echinacea purpurea 'Rubinglow':

    • From midsummer, glowing magenta-pink ray-florets form around the large, rust-coloured cone, forming long-lasting flowerheads, which remain interesting well into autumn. The flowers are very attractive to wildlife. Grows to 70cm. Supplied in a 9cm pot.
  • 3 x Saponaria × lempergii 'Max Frei':

    • Throughout summer, soft pink flowers smother the low-growing mounds of evergreen foliage. Sun-loving and drought tolerant once established, it looks wonderful tumbling over the edge of a raised bed or rock garden. Grows to 40cm. Supplied in a 9cm pot.
  • 3 x Eryngium giganteum 'Silver Ghost':

    • A prickly perennial forming a basal rosette of foliage from which branching leafy stems bear cylindrical flowerheads, that are surrounded by a ruff of prominent, silvery white bracts. The flowerheads can be added to fresh and dried arrangements. Grows to 60cm. Supplied in a 9cm pot.
  • 3 x Persicaria amplexicaulis 'Firetail':

    • Robust, clump-forming perennials that produce slender, bright red flower spikes on long, upright stems from midsummer above the handsome, semi-evergreen foliage. They will thrive in reliably moist soils. Grows to 1.2m. Supplied in a 9cm pot.
  • 3 x Phlox paniculata 'Blue Evening':

    • Trusses of fragrant, lilac-coloured flowers form on top of the upright, leafy stems from midsummer, attracting many beneficial insects. Very effective when teamed up with rich plums, purples and silver. Grows to 80cm. Supplied in a 9cm pot.
