A bulbous plant of the Iridaceae family, with about six species distributed in South Africa. The leaves are linear or sword-shaped and rooted. The flowers have six cup-shaped tepals and grow in a spike at the top of the stem. The most commonly cultivated species is S. tricolor, with orange flowers with black markings and a yellow flower tube. White, yellow, and scarlet varieties have also been developed. The bulbs are planted in the fall. As they require a temperature of about 4°C to survive the winter, they should be placed in a frame or indoors if potted, or in a sunny location with frost protection to overwinter if planted outdoors. When the above-ground parts turn yellow after flowering, the bulbs should be dug up and dried for storage.

アヤメ科の1属で,南アフリカに約6種が分布する球根植物。葉は線形または剣状で根出する。花は6花被片が杯形に開き,茎頂に穂状につく。おもに栽培されるのはスパラクシス・トリコロール S.tricolorで,花色は橙色の地に黒い斑紋 (はんもん) が入り,花筒部は黄色になる。白色や黄色,緋赤色の品種も作出されている。秋に球根を植付ける。越冬には4℃程度が必要なため,鉢植えの場合はフレーム内または室内に入れ,露地植えであれば日当りのよい場所に霜よけを施して越冬させる。花後に地上部が黄変したら球根を掘上げて乾燥貯蔵する。
