"I consider every plant hardy until I have killed it myself...at least three times" +More Dear all; I can't emphasize enough how important provenance is to gardeners such as myself who try to grow tender plants in cold climates. Too often plants in cultivation come from only a single or few introductions. I hope you'll try these two new accessions around the country. There are a couple of plants I'd sure like to get from the northern edge of their range instead of the southern plants available now. (or in Argentina's case the southern end of the range) and higher altitude too. Good luck and keep us posted about success and failure (hope not). Best Jim W. Dr. James W.

Now is a good time for a new round of updates. You can find the current aroid hardiness list at http://www.aroid.org/horticulture/hardy.html We would appreciate everyone who has input to send it to our research horticulturist Lynn Butler at lynn@plantdelights.com. Once will have compiled the additions, we will have the new list posted on the aroid-l website. We would like your comments on winter hardiness observations for these and any other aroid species. We only need information that extends the cold tolerance of a species. For the data to be useful, we require actual air temperature data that the plants survived without benefit of snow cover. Please understand that some Zone 8 plants can survive in Zone 3 if the snow cover comes early enough, so these results are skewed as they relate to the plants true ability to withstand cold. Thanks and we look forward to your information.

Typhonium (syn. Sauromatum) venosum has survived -18 °C cold this winter in my garden. It was planted in sand. Most of the small tubers grown on the mother and the mother tuber have been frozen, but one little tuber has survived. Formerly I forgot to collect them some years ago and it also survived in clay, but the biggest cold was not measured there (because I forgot...)

This directly correlates as to the depth that it's planted. This same rule applies to the tuberous members of Zantedeschia. Both hate clay soils which are prevalent in The South. I would recommend that these tubers be planted/covered at least 4"-6" deep in any zones colder than zone 8. They really don't like hot soil and might be late coming up in cooler zones but this will ensure that they winter over successfully if you forget to apply a generous mulch. It's worked for me for many years. BTW, cannas are quite reliable in zone 6a, even without a mulch. Perhaps the guides for hardiness should be re-written.
