Iris cedreti

What does Iris cedreti look like?

Iris cedreti is a compact, dwarf iris with pale yellow rhizomes and narrow, pointed leaves up to 23 cm long. The plant reaches 30–40 cm in height. Its striking flowers, about 18 cm across, have a white base covered with fine dots or veins in dark maroon, purple, or nearly black. Each flower shows a rounded, dark maroon signal patch and a beard of short brownish or purplish hairs. The standards are broad and slightly channeled, while the falls are ovate. After flowering, it forms a lobed seed capsule.

Where does Iris cedreti come from?

This iris is found only in Lebanon, growing wild along the Mount Lebanon range, especially in the Bsharri District. It was first described in 1972, and its name refers to the famous Cedars of Lebanon. The plant thrives at elevations between 1,300 and 2,000 meters on rocky, well-drained slopes. It is part of a group of closely related mountain irises, and genetic studies suggest these species may have diverged only recently.

When and how Iris cedreti blooms

Iris cedreti blooms in May, producing flowers at the top of short stems. It prefers sunny, rocky habitats with good drainage and terra rossa soil. In cultivation, it is rarely grown outside its native region due to its need for dry summer conditions. Propagation is possible by seed or division, with seeds requiring a period of cold followed by warmth. Seedlings are best grown in a mix of peat, perlite, and sandy loam.

How Iris cedreti is used

While rarely cultivated, Iris cedreti is sometimes grown as an ornamental plant. Its striking flowers have inspired perfume makers, such as Prada’s Infusion d'Iris Cedre. The plant is also a symbol of Lebanon’s unique mountain flora. However, it is not widely used in gardens due to its specific growing needs and conservation status.

Kinds of Iris cedreti

Iris cedreti is one of several Oncocyclus irises native to Lebanon’s mountains. These species are very similar, and recent studies found little genetic difference among them. The name is sometimes misspelled as I. cedretii or I. cedretti. No named cultivars are reported.

What Iris cedreti means

Iris cedreti is critically endangered, with much of its habitat lost to development, grazing, and tourism. It is protected in some reserves, and seeds have been stored at Kew’s Millennium Seed Bank. The plant is toxic if eaten or handled, causing stomach upset or skin irritation. Its beauty has inspired art and fragrance, but it remains a symbol of Lebanon’s threatened natural heritage.
