Thin leaves in typical iris "fans" produce tall stems that provide a multitude of cheery gold flowers flecked in orange in the height of summer. Each flower is short lived but he large inflorescence insures a number of flowers will be open during the three week flowering cycle. Highly attractive to smaller pollinator insects the resulting large showy black seeds are relished by songbirds later in the season.  Allow to reseed and consider this an annual in your gardens.
