Wistaria

Clouds dream and disappear;
Waters dream in a rainbow and are gone;
Fire-dreams change with the sun
Or when a poppy closes;
But now is the time of year
For the dark earth, one by one,
To show her slower dreams. And nothing she has ever done
Has given more ease
To her perplexities
Than the dreaming of dreams like these:
Not irises,
Not any spear
Of lilies or cup of roses,
But these pale, purple images,
As if, from willows or from pepper trees,
Shadows were glimmering on Buddha's knees.
