What is Campanula lasiocarpa
Campanula lasiocarpa or Iwagikyo (Scientific name: Campanula lasiocarpa) is an alpine perennial herb of the family Campanulaceae, genus Campanula, native to parts of Asia including Japan, and North America.
In Japan, it grows naturally in alpine rocky areas, screes, and grasslands from Hokkaido to the central regions.
Its height is 4–10 cm. The leaves are dull (without gloss), spatulate (narrow at the base), 2–5 cm long, with protruding serrations along the margins, and are arranged alternately.
From July to September, a solitary flower grows from the flowering stem. The corolla is campanulate (bell-shaped), 2–2.5 cm long (shorter than Campanula chamissonis), divided into 5 lobes at the tip, with no hairs on the lobes (unlike C. chamissonis which has hairs). The flowers are bluish purple (while C. chamissonis tends to be reddish purple), facing upward or slightly sideways (whereas C. chamissonis flowers face sideways).
Etymology of the name
The genus name Campanula means “little bell,” referring to the flower shape.
The species epithet lasiocarpa derives from Latin: lasi- (long soft hairs) + -carpa (fruit), indicating “fruit with long soft hairs.”
The Japanese name “Iwagikyo” means “bellflower (桔梗) that blooms in rocky places (岩).”
