Hens-and-chicks
屋顶长生花
Sempervivum Tectorum and Echeveria Elegans share the common name of Hens-and-Chicks. They both produce “chicks” — small and identical plants that are slightly offset from the mother (hen). But they look different. Echeveria Elegans forms flat and flowerlike rosettes, while Sempervivum Tectorum’s leaves tend to be flatter and more-pointed. The availability of different-colored hybrids makes them the perfect paint-box plants.屋顶长生草和月影有个共同的名字——“母鸡和小鸡（屋顶长生花）”。两种植物均产“小鸡”——形状相同的小型叶片，与母株（母鸡）稍微偏离。但两者看上去不一样。月影的花结呈扁平状，犹如一朵盛开的花朵；屋顶长生草的叶片则更加扁平，叶尖更尖。这两种植物的颜色富于变化，有多种混合颜色，是制作颜料的最佳选择。
Care tips
温馨护理贴士
Fertilize three times in summer with balanced fertilizer. Propagate by removing offsets and potting them. Although they look tough, they are easily scarred if water touches the foliage or if bumped. The soil should be allowed to dry slightly between waterings, as overwatering causes rotting. Water very little during winter dormancy.
夏天施三次肥料，每次用量均等。这种植物的繁殖可以剪取小莲座形叶盘，然后插到花盆里。尽管看起来很结实，但它的叶片一旦接触到水或者受到碰撞，就很容易受伤。应等土壤稍微干透后再浇水，过度浇水会导致其腐烂。冬天休眠期应少浇水。
