Parodia chrysacanthion

Parodia chrysacanthion is native to Jujuy province of Argentina, a place known to cactus lovers for many fine plants growing there. This plant grows large for the genus, forming a fat disk wrapped in dense yellow spines. The name  'chrysacanthion ' refers to the golden spines color here. There is also a nice white-spined form of that species in cultivation.
This plant is one of the more 'difficult' Parodias and easy can loose it's roots in the soil that is too dense and if watered at the wrong time. Apart from that it is more or less easy plat, growing with moderate rate and blooming readily. In my greenhouse it appreciates light shading.
