Persicaria thunderbergii's
flower color varies continuously from deep red purple to white; the
pure white ones are called Persicaria
thunderbergii f. albiflora,
which are rare. Whitish ones, however, grow relatively abundant,
where the red-purple, the majority, inhabit. The habitats are
constantly dump-to-wet places like water's edges or fringes. Bloom
time: July-October. |
