Beverly Sills Bearded Iris blooms profusely in mid-season and often reblooms later, too. Pale coral petals with light apricot "beards" make these award-winning blooms true beauties. These plants grow quickly and top out at 32 – 38 inches tall. Semievergreen leaves set off the delicate flowers and add visual interest when they aren't in bloom. Beverly Sills Bearded Iris is hardy in Zones 4 – 9.
