These Aspens are 4" - 5" in height.  Foliage is mixed orange and yellow.   These really make a statement next to rocks and pines.   These give the allusion of tiny leaves in various stages of Fall color.   The third photo shows the marvelous color in high mountain areas like Colorado and Alaska.   Refer to photo #4 for the four color phases I make (Green, Hint of Yellow, Yellow, Orange/Yellow).   As seen in real photo #3, all 4 phases can be adjacent to each other simultaneously.
