Dear Sir/Madam:

I'm not sure exactly what type of plant this is but I do know some folks who probably do.  If you send your picture to the Maricopa County Cooperative Extension "Master Gardener" plant hotline, I'm sure someone there can assist.  Their email address is <personal data hidden>.  I'm fairly sure they can help.  If not, write me directly at <personal data hidden> and I'll be sure to find someone who can help.
