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 larger leaves on the lower parts. The middle part of the
leaves is 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, are generally
set singly on branch tips. Involucres are about 1cm long, about 2cm
wide, and hemispheric; involucral bracts are arranged in 4 rows.
Bloom time: July-September. |
