Persicaria bistorta 'Superba' syn. Polygonum bistorta 'Superbum'

 

Red Bistort 'Superba'

Persicaria are commonly known as knotweeds or smartweeds. Flowers in shades of pink or white appear late in the season on these hardy, herbaceous perennials. They are easy to grow and ideal for boerders or as ground cover. The best flower and leaf colour is achieved when grown in full sun. Superba is a fast growing plant that is semi-evergreen. The flower spikes produce tightly packed bell shaped flowers in pale pink and white looking like a bottle brush in shape.

Flowering

From Mid Summer TO Late Autumn

Most species of Persicaria are in flower through the summer months between mid summer and late autumn.

 

Planting Outdoors

From Early Spring TO Mid Spring

Put pot grown plants into the garden in full sunny or partially shaded site. They prefer a moist and fertile site if placed in a drier position they will need watering through hot periods.

 

Propagation by Division
