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 about 1cm in diameter. Before sprouting,
flower stalks rise above the ground and set flower heads in a
corymbs way. The flower stalks come out with many bracts with
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. |
