I had this for several years, kept in a large pot in a cold greenhouse. I grew it in a good gritty 'river soil' mixed with lots of leafy compost. It can survive very low temperatures in the UK and produced a spathe reliably every year, although a repot occasionally is advisable to give it a boost with fresh compost. It is later to show than many other Arisaemas, it will place itself very deep in a deep pot so don't panic if it's slow to show although I have at times scratched down to see if all is well you have to be careful not to knock off it's new growth tip.
I had never fed it as it got sufficient nutrients from the compost and I believe artificial feeding can often reduce hardiness. It managed to get through a very cold winter in the UK in 2009/10 but the winter of 2010/11 was an exceptionally cold winter with temperatures below freezing continually for 7 weeks dipping as low as -17C, that killed it! Worth another try though!
