別名:金粉油點木
龍血樹屬常綠灌木,原產西非熱帶氣候區。本種是選拔出葉片黃斑明顯,且具有黃白條紋的園藝品種。莖自基部叢生,纖細直立,末端因葉片重量歪斜或下垂,長0.6~1.5m。橢圓形葉對生或3~4枚輪生,長6~10cm。繖型花序,白色半透明花朵,夜間芳香宜人。橙紅色漿果球形,直徑約1cm。
An evergreen shrub in the genus Dracaena, native to the tropical zone of West Africa. A cultivar with distinct yellow markings and yellow white stripes spreading on the leaves. Stems clustered from the base, slender and erect, 0.6m to 1.5m long and the ends skewed or drooped due to the weight of leaves. Leaves oval-shaped, opposite or 3~4 whorled, 6~10cm long. Umbrella-shaped inflorescence, white translucent flowers emit pleasant fragrance at night. Orange-red berry spherical, about 1cm in diameter.
半日照環境,全日照處受陽光曝曬容易葉片焦黃。介質需有兼具透氣與保水力,以培養土種植為宜。不耐旱,介質略乾就澆水。春至秋施用一次長效性綜合肥料。冬季低溫期生長停滯。繁殖使用扦插法。
Partial-sun environments preferred as the leaves may turn yellowish when exposing to full-day sunlight. Culture soil with good aeration and water retention capacity is recommended. Not drought-tolerant, water the soil once it slightly dries. Apply a slow-release compound fertilizer from spring to autumn. Growth stagnant during the low temperature period in winter. Propagated from cuttings.
植株形象類似竹子,可以彌補竹子造型植物在室內栽培設計應用的空缺。本品種葉色金黃醒目,用於室內造景或盆栽組合設計都有良好的效用,也適合剪下枝葉作為花藝設計材料。
The bamboo-like plant is often used as a substitute of bamboo plants in interiorscaping projects. The golden foliage is highly ornamental and is widely used for interiorscaping or combined planter designs. The cuttings of branches and leaves are also widely used as flower arrangement materials.
