Dear Rick
in my experience green fresh leaves are good source for total DNA 
extraction. You may try some from your garden/window but remember best 
results from expanding tissues. Or you may get some seeds, barley, wheat, 
rice or maize and let them germinate for one week. As I am working with 
cereals I will be happy to hear about your non-phenol/chloroform
