介绍: 蒂亚,也称绿焰, Sedeveria ‘ Letijia’。景天科、景天属与拟石莲花属杂交的园艺品种。
绿焰、蒂亚,多年生小型肉质草本。生长力旺盛,且较快,易从茎干底部长出分枝,形成群生株。叶子倒卵状楔形,背面有龙骨突起,表面光滑,叶子的边缘及背部龙骨线处,有细微短毛状物分布,这或许是“绿焰”的来由。夏季青绿色,深秋、整个冬季和初春,叶缘乃至叶片的大部分变成红色,漂亮的玫瑰红色,或鲜艳的朱红色。叶片在光照充足时,排列较紧密,呈莲座状。老叶易脱落,老茎易长出气生根。春季开花,穗状花序从叶间抽出,花小,钟形,五角星状,白色,或黄色。
绿焰、蒂亚,喜温暖、干燥、通风和阳光充足的环境。耐旱、耐寒、耐阴,适应性强,但不耐烈日暴晒。一般无明显的休眠期。生长期可充分浇水,夏季高温时应注意遮荫,并少量浇水,同时,加强通风也是必不可少的。一定要给予植株充分光照,光照不足容易徒长,叶子变得松散、单薄。冬季移入室内阳光充足处养护。介质的要点是疏松,排水性能良好,较肥沃,建议在盆底加入适量的骨粉作为基肥。繁殖采用扦插,叶插和枝插都行。
