It seems like AZ finally got some rain!  A good plant now in September is rain lily white and pink (Zephyranthes candida and Zephyranthes grandiflora). With our warm temps and rains in July, August and September this plant opens up its blooms!!!  When it is not in bloom it looks like soft green grass. It needs a little filtered shade in the afternoon but can be watered in the summer once every 5 days.  Landscaping in Mesa and Gilbert Arizona.
