| As the arisaemas are mixed, their hardiness could be variable and it would be better to err on the side of caution until they have grown and multiplied enough to afford taking risks. The Sauromatum (New name is Typhonium venosum), does survive outdoors in many parts of the country but excessive cold or wet conditions can kill them off. As with most other arum type plants, better results are obtained by starting them into growth early. This gives a much longer growing period to fatten the tuber which will then produce a large number of offsets. Personally, I think they look much nicer in a large pot but must be given plenty of food and drink. Moriati |
