Bowl tube iris (or Ground iris) in central California

Bowl tube iris on the west side of Mount Hamilton

 

Iris macrosiphon growing at about 2000 feet elevation west of the peak along the Mount Hamilton Road, Santa Clara County, California. Some flowers grow very close to the ground (thus the name “ground iris”). The name “bowl tube iris” comes from the bowl-shaped top of the flower tube - the petals separate right along the rim.
