We are updating our list of temperate aroid hardiness; the list follows.  We
are interested in actual cold temperatures (WITHOUT snow cover), the zone
and city/state location in which these temperature were recorded, and the
plant recorded.  Results will again be posted to the IAS website.  Also
include any other notes related to aroid cold survival and reply to Petra's
email address (petra at    Thanks for your help with this
