Himalayan Fleeceflower

Fleeceflower in Summer bloom

Himalayan Fleeceflower or Knotweed
( Persicaria affinis syn. Polygonum affine syn Bistorta affinis )

an unusual flower for the garden
it is suited to both full sun and semi-shade
once it is established it is a very hardy and dry tolerant plant

creeping across the ground striking down new roots this plant will quickly settle as a good strong ground cover
leaves are slender rounded blades 
deep green with slashes of reddish-purple for new leaves and Autumn colouring as well as an indicator that your soil is drying out !
it is a herbaceous perennial so expect dieback in Winter where you get heavy frosts
otherwise you can expect the foliage to stay around in gentler climates

reddened leaves for many reasons
spikes of dusky dark pink, turning to soft pink flowers appear in mid Summer
and continue to repeat flower through Autumn
flowers grow taller as the season progresses
starting at about 10cm and reaching 25cm in late Summer
