Petasites japonicus
is a dioecious perennial that propagates by extending rhizomes.
Leaves are kidney-shaped orbicular, 15-30cm in width, with
deep-heart-shaped bases; petioles grow to as long as 60cm and are
about 1cm in diameter. Before appearing, the flower stalks rise
above the ground and form a corymb of flower heads. The flower
stalks emerge with numerous bracts featuring prominent parallel
venations. Male plants grow to 10-25cm tall and set many
yellow-white flower heads, while females initially have dense flower
heads but grow to approximately 45cm afterward. Bloom time:
March-May. |
