A deciduous shrub of the Rosaceae family (APG classification: Rosaceae). It grows to a height of 1-2 meters, forming a clump, with the ends of the branches slightly arching. The leaves are alternate, diamond-lanceolate or diamond-oblong, 2-4 cm long, pointed at the tip, and narrowing to a wedge shape at the base. The upper half of the edge is sawtoothed, both sides are hairless, and the underside is white. In April and May, a round-shaped corymb about 3.5 cm in diameter blooms at the end of the twigs, and about 20 small white flowers bloom. The flowers are about 1 cm in diameter, with five almost circular petals, and the sepals are egg-shaped triangular with pointed tips and hairy edges. There are 20-25 stamens and 5-6 pistils. The fruit consists of five small capsules that ripen, turn brown, and split open around October. Native to central China, it has been cultivated in Japan since the early Edo period. It is widely planted as a garden tree from Hokkaido to Kyushu, and has also been used for flower arranging since ancient times. It is not picky about soil and grows well in sunny places. It is propagated by cuttings and division. It resembles the Temaribana (Viburnum gracilis) of the Caprifoliaceae (APG classification: Viburnum family), but was given this name because its inflorescence is small and spherical. It has also been called Suzukake since ancient times. One variety is the double-flowered Yaeko Demari.

バラ科(APG分類:バラ科)の落葉低木。高さ1~2メートルで株立ち状になり、枝先はやや弓形になる。葉は互生し、菱(ひし)状披針(ひしん)形または菱状長楕円(ちょうだえん)形、長さ2~4センチメートルで先はとがり、基部はくさび形になって狭まる。縁(へり)の上半部に鋸歯(きょし)があり、両面無毛で、裏面は白色を帯びる。4~5月、小枝の先に径約3.5センチメートルほどのまり状の散房花序をつけ、20個内外の白色の小花を開く。花は径約1センチメートルで、ほぼ円形の花弁が5枚あり、萼片(がくへん)は卵状三角形で先がとがり、縁に毛がある。雄しべは20~25本で、雌しべは5、6本ある。果実は5個の小さい袋果(たいか)からなり、10月ころ、褐色に熟して裂ける。 中国中部の原産であるが、日本では江戸時代初期から栽培している。北海道から九州まで広く庭木として植え、またいけ花に古くから用いられている。土地を選ばず、日当りのよい所でよく育つ。繁殖は挿木、株分けによる。スイカズラ科(APG分類:ガマズミ科)のテマリバナ(オオデマリ)に似ているが、花序が球形で小形なのでこの名がつけられた。古くからスズカケともよばれている。品種に八重咲きのヤエコデマリがある。 [小林義雄 2020年1月21日] [参照項目] |春、小枝の先にまり状の白い散房花序をつける©Shogakukan"> コデマリ 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
