Luminous leaves

The young leaflets of the honey locust (Gleditsia triacanthos 'Sunburst') are a gorgeous golden yellow, contrasting with the blue sky of a sunny spring day.

The backlit trees on a hillside show the contrasting greens and textures of their spring growth - in the front is a golden elm (Ulmus procera 'Louis van Houtte"), behind it an array of deciduous and evergreen trees in bright contrast.  

The finely cut bright red young leaves of a Japanese maple (Acer palmatum) are ruffled by spring winds.
