Persicaria lapathifolia   Pale Persicaria C DD N

Persicaria lapathifolia

The diagnostic for this plant is the presence of small glands on the flower stem and on the perianth (sepals) but I first look out for a pale greenish flowered Persicaria often growing with P. maculosa (Redshank) and P. hydropiper (Water Pepper). In my experience a healthy plant will often be larger and more straggly than Persicaria maculosa which can have confusing pale forms. I haven't yet seen any pink forms of P. lapathifolia as illustrated in Stace's DVD.

P. lapathifolia is very common throughout England and Wales less common in Ireland and records decrease as you go north, so it is uncommon in the Highlands and the far north of Scotland.
