Quaking Aspen (Populus Tremeloides)
Works best above 7000ft, although they do somewhat well in the city of Santa Fe.
Likes moist, rich soil, cool temperatures. Plant on north or east side of homes in clumps for best results.
Deep green leaves through excellent yellow fall color, and with a slight wind, the leaves seem to be dancing.
Downfall, they can get black spot on leaves.
