USDA touts 'power trees'
Scientists at the U.S. Nat'l. Arboretum have spent the last 4 years studying 
trees that can stand up to the rigors of urban environments. The Power Trees 
Project identified cultivars that exhibited pest resistance and tolerance 
for environmental extremes. Trees that made the cut include Ulmus 
'Frontier,' Prunus 'Dream Catcher' and Lagerstroemia 'Natchez.'
