Persicaria amplexicaulis 'Alba'
A white-flowered selection with pure white blooms held in long, slender spikes. The slowest to establish and latest to begin flowering within this group, often not starting until late July. Individual flowers are spaced along the spikes creating a more refined appearance than densely-packed cultivars.
Maintains upright growth without invasive tendencies. Clumping habit integrates well with surrounding plants. Adaptable to various soil conditions except dry sites. The white flowers and refined character make it valuable for lighter colour schemes. Takes time to settle in but becomes reliable once established.
