I find it very easy indeed, more so than any other Arisaema, very reliable in both flower and seed and good in either pot, trough or garden. Mine grows to a max height of about 15cms. It makes no demands re composts, just a reasonable, humusy compost, well drained and it doesn't mind full sun so long as the compost is a little moist. Shade OK too.
Our new profiles don't give location of where we come from (unless yet again I'm missing something obvious) so maybe my climate is easier than yours Pontus, but I'm sure you should have no problems with it. I've just cleaned this year's seed if anyone would like some.
