Another favourite is arisaema tortuosa, flowering in the shade house.A few years ago, I had quite a few varieties, but due to some neglect, they have dwindled down to a small handful. I have wasted so much money on arisaema seed, that I probably could have gone to the Himalayas or China or the US of A and seen them growing in the wild. Apparently, arisaema seed looses its viability very quickly and should be stored moist, or sown immediately.Anyone having success with this group?
