Hylotelephium spectabile (syn. Sedum spectabile) is a species in the stonecrop family Crassulaceae

Hylotelephium spectabile (syn. Sedum spectabile) is a species of flowering plant in the stonecrop family Crassulaceae, native to China and Korea. Its common names include showy stonecrop, iceplant, and butterfly stonecrop. Growing to 45 cm (18 in) tall and broad, it is an herbaceous perennial with alternate, simple, toothed leaves on erect, unbranched succulent stems and has a tuber root rhizome. The leaves are usually arranged opposite or in threes, simple and more or less wedge-shaped at the base, and frosted blue above; they are 2.5 to 10 cm long and 0.8 to 5 cm wide. The leaf margin is smooth or serrated towards the tip. Stipules are missing. The star-shaped pink flowers are borne in flat cymes 15 cm (6 in) across from summer until first frost. The many-flowered, zymous inflorescence is about 7 to 11 cm wide. The hermaphrodite, radially symmetrical flowers have a diameter of about 1 cm and are usually five-fold. The sepals are about 1 cm long. The petals are (rarely 5) usually 6 to 8.5 millimeters long. There are two circles 6 to 8 mm long stamens, which are significantly longer than the petals. The anthers are purple. The free carpels are about 3 mm long. The stylus is about 1.2 mm long. This self-fertile species is pollinated by insects. The specific epithet spectabile means “showy“. This plant is valued in cultivation, and numerous cultivars have been produced. The species and the cultivar ’Brilliant’ have both gained the Royal Horticultural Society’s Award of Garden Merit. It was introduced to France in the mid-1860s. Easily grown in pots, it is widely used in decorative beds, rock gardens in particular, or in pots, especially in China where this plant is very widespread. Its flower is used by florists in the composition of bouquets. It is a full sun, drought tolerant, cold- tolerant honeycomb plant (down to -15 ° C when fully established). This sedum multiplies by division in spring. It has also been widely used as a laboratory plant where it is studied got its synthesis of sedoheptulose. Phytopurification and phytostabilisation of soils: the effects of heavy metals on the plant and their kinetics in the parts of the plants have been studied. Hylotelephium spectabile (syn. Sedum spectabile) 是景天科景天科的一种开花植物，原产于中国和韩国。它的常见名称包括艳丽的景天、冰草和蝴蝶景天。 它长到 45 厘米（18 英寸）高和宽，是一种多年生草本植物，在直立、不分枝的肉质茎上具有互生、简单、带齿的叶子，并有块茎根茎。叶通常对生或三叶排列，基部单叶或多或少呈楔形，上部呈磨砂蓝色；它们长 2.5 到 10 厘米，宽 0.8 到 5 厘米。叶缘光滑或向尖端呈锯齿状。托叶缺失。 从夏季到第一次霜冻，星形粉红色花朵在 15 厘米（6 英寸）的扁平聚伞花序中生长。多花的酶状花序宽约7至11厘米。雌雄同体，径向对称的花朵直径约 1 厘米，通常为五倍。萼片长约1厘米。花瓣（很少有 5 个）通常有 6 到 8.5 毫米长。雄蕊有两个圆形，长 6 至 8 毫米，明显长于花瓣。花药是紫色的。游离心皮长约 3 毫米。触控笔长约 1.2 毫米。这种自我繁殖的物种由昆虫授粉。 特殊的加词“壮观”的意思是“艳丽”。 这种植物在栽培中很有价值，并且已经生产了许多栽培品种。该物种和栽培品种“Brilliant”都获得了皇家园艺学会的花园优异奖。它在 1860 年代中期被引入法国。 它很容易在花盆中种植，广泛用于装饰床，特别是岩石花园或花盆，特别是在这种植物非常普遍的中国。它的花被花店用于制作花束。它是一种阳光充足、耐旱、耐寒的蜂窝植物（完全成熟时可降至-15°C）。这种景天在春天乘以分裂。 它也被广泛用作实验室植物，研究它合成景天庚酮糖。土壤的植物净化和植物稳定：研究了重金属对植物的影响及其在植物各部分的动力学。 Hylotelephium spectabile（syn。Sedumspectabile）は、中国と韓国に自生するベンケイソウ科の顕花植物の一種です。その一般的な名前には、派手なマンネングサ、アイスプラント、蝶のマンネングサが含まれます。 高さと幅が45cm（18インチ）に成長する草本の多年生植物で、直立した枝分かれしていない多肉植物の茎に交互の単純な歯の葉があり、塊茎の根茎があります。葉は通常、反対側または3つ&
