An annual plant of the Asteraceae family native to Australia. In summer, it produces flower heads wrapped in dry involucres at the top of the stem. The stems are characterized by wing-like protrusions. The ones sold by florists as "Kaizai-ku" are actually the horticultural variety Helichrysum bracteatum Andr. (English name: strawflower), a different genus of the Asteraceae family also native to Australia, called "Emperor Shell Craft" (illustration). This plant is 80-90cm tall. It branches roughly and produces solitary flower heads at the ends of the branches in summer. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
