Blue flag has long narrow green leaves that arch and show blue or indigo flowers.
Description
Weak stems can be simple or branch somewhat. They grow up to three feet tall and arch a little.
Showy blue or indigo flowers bloom in May. The three outer parts of the petals are oval or egg shaped, grow one to one and a half inches wide, and have a distinct yellow midrib. The three inner sections of the petals are egg shaped and smaller than the outer sections.
Long green leaves can be two and a half feet long, are limp, and either arch or fall to the ground. They are narrow and come to a sharp point at the tip.
