生石花广泛分布在降水很少的南非干燥地区。由于这种特殊的气候特点,其中的大多数品种在夏季炎热时期进入休眠状态,以避免水分的流失,并抵御烈日的照射。自上世纪80年代初生石花陆续引入我国,经过长期的栽培驯化,目前国内繁殖的生石花的夏休眠习性略有改变。特别是近几年来,多数爱好者直接从美国和欧洲等花卉公司购买成株或繁殖材料,并与我国以往繁育的生石花后代杂交,使得目前的生石花习性各异,难于掌握其夏休眠特性,这让很多爱好者颇为烦恼。 Rock flowers are widely distributed in the dry areas of South Africa with very little precipitation. Because of this particular climatic feature, most of these species are dormant during the hot summer months to avoid moisture loss and to resist the sun’s exposure. Since the early 80s of last century, stone flower was introduced into our country one after another, and after a long period of cultivation and domestication, the summer dormancy habits of domestic stone flower slightly changed. In recent years, most enthusiasts, in particular, purchased adult or propagation materials directly from flower companies such as the United States and Europe and crossed with the offspring of previously-born kamaboko in our country so that current kamakura habits are different and it is difficult to grasp their summer dormancy characteristics , Which makes a lot of fans quite troubling.
