Boyce Thompson Arboretum, Superior, Arizona, USA

24 April 2013

Wildflower in botanical garden

 

Synonyms:

  • Cistus x hybridus

Comment:

This perennial, evergreen shrub is a natural hybrid which is non-native to the US. Its large, showy white flower becomes UV-absorbing, so bees see it as blue-green. There seems to be some iridescence along the petal edges which gives the impression of light rays emanating from the center.
