Frequently Asked Questions

What is a bearded iris?

The bearded iris is not a single species but the largest group within the genus Iris, uniting various species and cultivars that share an anatomical feature: the lower petals (falls) bear a strip of bristles in a contrasting color, resembling a beard.

All bearded irises are perennial plants with strong rhizomes — typically 1.5–2 cm thick, fleshy, growing horizontally underground with clear annual swellings. Some varieties have rhizomes with a distinctive scent (violet aroma). Leaves are typically grey-green, sword-shaped, two-ranked, and flat. The flower stalk is upright, tall, and branched. The flower consists of six petals in two layers: three rise upward — called standards, and three arch downward — called falls. Colors and shades vary widely.

Bearded Iris Classes

• MDB — Miniature Dwarf Bearded (under 20 cm)
• SDB — Standard Dwarf Bearded (20–40 cm)
• IB — Intermediate Bearded (40–70 cm)
• MTB — Miniature Tall Bearded (40–70 cm, smaller flowers)
• BB — Border Bearded (40–70 cm, larger flowers)
• TB — Tall Bearded (over 70 cm) — the most popular class

Growing tips

Bearded irises love full sun and well-drained soil. Plant rhizomes shallow, so the top is partially exposed to the sun. Avoid overwatering and heavy mulching, which can cause rot. Best planting time: July–September.
