ORANGE PETALS: (O. D. Niswonger, R. 1991). Sdlg. IB 13-88. IB 25" (64 cm) M. "S. pinkish orange; F. orange; beards orange Oriental Blush X unknown, Cape Iris 1991 HM 1993" The preceding description was taken from the American Iris Society's Check List Data Base. This little IB grows short here at 18-20", but what it lacks in height, it makes up for in blooms! Very vigorous, fast growing and covered in flowers. Begins to bloom here near the last week in April. Very hardy, quickly multiplies increase, and never disappoints! I recommend highly!
