Inula salicina var. asiatica is a 60-80cm tall perennial
herb growing in sunny, damp fields and mountains, propagating by
extending long rhizomes. Stems are slender and stiff, with somewhat
dense hairs. Radical squamous leaves are gone in flowering time, and
so are slightly big-sized leaves on lower parts. The middle part of
leaves are 5-8cm long, 1-2cm wide, and long oblong-like lanceolate,
with pointed tips, bases embracing the stems, and sparse serrations
on margins. Flower heads, yellow, 3.5-4cm in diameter, set
themselves generally singly on branch tips. Involucres are about 1cm
long, about 2cm wide, and hemispheric; involucral bracts arrange
themselves in 4 rows. Bloom time: July-September. |
