[Aroid-l] Ambrosina bassii

From: soukupvg at email.uc.edu (Victor Soukup) on 2007.10.27 at 19:08:13(16617) Hi--- Regarding the cold hardiness of Ambrosina bassii, a few years ago I received some seed from Fausto Ceni for my study of seed lipids, but there were enough seeds for me to also plant some. In their second year I planted them outside under partial summer shade and quite open to the sky in winter. In November one plant bloomed and the leaves on the others continued to look healthy. During this time the temperatures dipped to minus 8 degrees Celsius at times and on two occasions the leaves and the flower were barely covered with snow. The next year the plants again emerged although there were fewer in number. One bloomed again but the predations of animals in the area cut the population to one plant the third year. All were gone the following year. These data are for Cincinnati, Ohio where we have very fluctuating weather and have had a low of minus 23 degrees Fahrenheit (four days) and highs of 100 in the last 30 years. However, Magnolia grandiflora came through the record cold, albeit with a little damage, The zone is listed as 5 or 6 but most of the time we experience 7 or 8. It seems that with a little protection and careful siting, that Ambrosina could be grown in zone 7. Typhonium (Sauromatum) venosum grown from Cameroon collected seeds grows outdoors here --- for 12 years. You must try to find out.
