A bulbous plant of the Iridaceae family (APG classification: Iridaceae) planted in autumn. It is also called Asagi suisuisen. Native to South Africa. The bulb is a long, spindle-shaped corm covered with a fibrous membrane that germinates immediately after planting and overwinter by growing 5 to 6 linear, long, thin leaves. Outside of warm regions, it is grown as a cut flower or potted plant in a frame or greenhouse. The flower stalk is 30 to 40 cm tall, long and thin, and produces about 10 fragrant flowers in a funnel shape. The flowers come in a wide variety of colors, including white, yellow, peach, red, orange, and purple, and are mainly single-flowered, but semi-double and double-flowered varieties are also available. The flowering season is November when cultivated under low temperature treatment in a refrigerator. To make it bloom after January, do not perform low temperature treatment, but plant it in early to mid-September, expose it to a light frost in early November, and then place it in a greenhouse or frame, and it can be enjoyed from around March. The main varieties include White Mary (white), White Sea (white), Rheinbelt Golden Yellow (yellow), Excelsia (yellow-white), Rosemary (dark pink), Shisen (purple), Red Lion (vermilion red), and Diana (white, double-flowered). Propagation is by bulblets. For potted plants, plant 5 bulbs in a No. 5 pot. Keep the plant as short as possible to prevent the leaves from growing too long, and use clayey loam soil mixed with compost or peat moss to keep the stems and leaves firm. As the bulbs have little stored nutrients, apply plenty of base fertilizer and top dressing. The main production areas in Japan are Hachijojima and Okinoerabujima, where they produce rich, high-quality bulbs that wake up from dormancy quickly and germinate quickly. [Hideaki Iwai May 21, 2019] The leaves are linear and elongated, and the flower stalk is 30-40cm tall. It produces several elongated funnel-shaped flowers. The flowers come in a wide variety of colors, including single, semi-double, and double flowers. ©Seishohmaru "> Freesia Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
アヤメ科(APG分類:アヤメ科)の秋植え球根草。アサギスイセンともいう。南アフリカ原産。球根は細長い紡錘状の球茎で繊維質の被膜に覆われ、植え付けるとすぐ発芽し、5~6枚の線形の細長い葉を伸ばして越冬するので、暖地以外ではフレームか温室で切り花、鉢物栽培する。花茎は高さ30~40センチメートル、細長い漏斗(ろうと)状で香りの高い花を約10個開く。白、黄、桃、紅、橙(だいだい)、紫色など花色は豊富で、一重咲きを主に、半八重、八重咲きもある。花期は冷蔵低温処理栽培で11月。1月以降に開花させるには低温処理を行わず、9月上旬から中旬に定植し、11月上旬に薄い霜に当ててから温室、フレームに入れると、3月ころから観賞できる。おもな品種にホワイト・マリー(白色)、ホワイト・シー(白色)、ラインベルト・ゴールデン・イエロー(黄色)、エクセルシア(黄白)、ローズマリー(濃桃色)、紫泉(紫色)、レッド・ライオン(朱赤色)、ダイアナ(白色、八重咲き)などがある。繁殖は子球による。鉢植えは、5号鉢に5球植えとする。葉が伸びすぎないようなるべく草丈を低くし、茎葉を堅く育てるため、用土は粘質壌土とし、堆肥(たいひ)か「ピートモス」を混ぜるとよい。球根の貯蔵養分が少ないので、元肥と追肥を十分に施す。日本における主要生産地は八丈島、沖永良部(おきのえらぶ)島で、充実した良質の球根がつくられ、休眠から早く覚めるので、発芽が早い。 [岩井英明 2019年5月21日] 葉は線形で細長く、花茎は高さ30~40cm。細長い漏斗状の花を数個つける。花色も豊富で、一重咲きのほか、半八重や八重咲きもある©Seishohmaru"> フリージア 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 |
