About Bearded Iris

Iris germanica, the tall bearded iris, produces spectacular flowers with three upright 'standard' petals and three drooping 'fall' petals, decorated with fuzzy 'beards.' The flowers come in an enormous range of colors and patterns — from pure white through every shade of blue, purple, pink, orange, yellow, and near-black, often with contrasting falls and standards. Growing from thick rhizomes, they bloom in late spring and can reach 90 cm tall. Over 30,000 cultivars are registered. The iris is named after the Greek goddess of the rainbow, and the flower lives up to the name.

History

Illustrated historical scene for Bearded Iris

Iris germanica is not a true wild species but a complex ancient hybrid cultigen of Mediterranean Europe, its exact parental history obscure. It is the classic 'tall bearded iris' of cottage gardens, and is the iris behind the French fleur-de-lis heraldic symbol, adopted by the French kings from the 12th century. Its rhizomes are the source of 'orris root' (iris root powder), which when dried and aged for several years develops a violet-like fragrance used as a base-note fixative in traditional perfumery — and still used at ruinous cost in luxury perfumes today; aged orris butter is one of the most expensive natural perfumery materials on earth.

Modern iris breeding began in earnest in France around 1830 (Lemon, Vilmorin), expanded dramatically in early 20th-century US breeding, and has produced over 60,000 registered cultivars. Moderately toxic to pets due to rhizome irritants. The iris has been a symbol of royalty since ancient Egypt, where it appeared in temple carvings 3,500 years ago.

The French fleur-de-lis — symbol of French monarchy since the 5th century — is widely believed to represent an iris, not a lily. King Louis VII adopted it during the Second Crusade. 5 uses it. Florence, Italy, built a perfume industry around orris root from I. pallida and I. germanica, with the iris becoming the city's emblem on its coat of arms.

Symbolism & meaning

What It Symbolizes

The Bearded Iris has meant faith since pharaonic Egypt, where it was carved into temple walls for the journey to the afterlife, and later became the fleur-de-lis of French royalty and the messenger of the goddess Iris itself. Its three upright standards have stood for wisdom, valor, and faith on countless heraldic shields. It is the flower that empires and religions have chosen to mean: trust the path.

Faith — Associated with royalty and heaven since ancient Egypt, representing trust and wisdom

Where the Name Comes From

Iris from the Greek goddess of the rainbow, for the flower's color range. Germanica means 'of Germany,' though it originated in the Mediterranean.
