Jazzamatazz was hybridized by Heidi Blyth in 1986 down under in Pearcedale, Victoria, Australia, but it also grows in the U.S. Zones 3 to Zone 8b. It is very hardy here in Wisconsin. Jazzamatazz is happy in full sun to part shade. Mine is in an east-facing location. This iris is registered as growing up to 15" tall, but mine rarely gets taller than about 10." In my yard Jazzamatazz reliably blooms in mid-May every year.
