Fill the hole with soil and heel well in. Water immediately. Persicaria amplexicaulis (red bistort) will thrive in a sheltered, sunny spot in humus rich, nutritious and free draining soil.

Red bistor in the border

Red bistort is becoming ever more popular for in borders. The tall flower spikes look great anywhere. Because of its height it’s a plant that makes a good backdrop at the back of the border. A versatile plant that makes a lovely combination with lavatera, peonies (Paeonia) and mallow (Sidalcea oregana) 'Partygirl'.


In spring apply a good mulch of garden manure. The flower heads could use a little support in places that get a lot of wind. Place a stake at the back of the plant and tie them on with garden string. Make sure the soil around the roots does not dry out. Snip off spent flower heads to encourage reflowering. Clay soil shouldn't need much fertilising. They do not like too much disturbance but you should divide the clumps  every 3 years or so to keep it vigorous and producing nice firm flower stems.
