ssp_japonica is a perennial herb, 0.5-1.2m in height,
inhabiting sunny, moist/damp, high places in mountainous regions,
forming colonies. Rosettes, with long pedicles, are in the shape of
a lanceolate to long-oblong, with the tips pointed and the bases
abruptly tapering off to both sides of long pedicles, which grow to
become wing-like. On-stem leaves are petiole-less; they embrace the
stems at their bases. Stem apexes produce cylindrical spikes with
numerous dense, white to light red flowers. Bloom time:
July-September. |
