Gilboa Iris

What does Gilboa Iris look like?

The Gilboa Iris grows up to 60 cm tall, with a slim stem carrying a single large flower above grey-green, sword-shaped leaves. Its blooms reach about 10–12 cm across, displaying deep purple, violet, or brownish tones, often marked with veins or spots over a lighter background. Each flower has three broad, recurved outer petals and three upright inner petals. A dark patch sits at the base of the outer petals, with a row of short hairs that can be dark purple, white, or yellow-tipped. Some rare forms have pale yellow or golden flowers.

Where does Gilboa Iris come from?

This iris is native to the hills and shrublands of northeastern Israel and Palestine, especially around Mount Gilboa, and extends into northwestern Jordan. It was first collected in the 1870s and named after botanist William Amherst Hayne. The plant was described in scientific journals in the late 19th century. Closely related to other Oncocyclus irises, it was once thought to be a form of another species, but genetic studies have confirmed it as distinct.

When and how Gilboa Iris blooms

Gilboa Iris flowers from March to April, growing in rocky, limestone-rich soils and Mediterranean shrublands. The plant forms clumps from underground rhizomes and produces new leaves in spring, which wither after summer. Its seeds can remain dormant for years, waiting for favorable conditions. The iris is rarely grown in gardens because it needs dry summers and specific soils.

How Gilboa Iris is used

The Gilboa Iris is a symbol of national pride in Palestine and is protected in both Israel and Palestine due to its rarity. It is not widely cultivated but is sometimes grown for its striking appearance. In the past, wild plants were picked for decoration, which led to a decline in numbers. Conservation efforts now focus on protecting its natural habitat and educating the public.

Kinds of Gilboa Iris

Most Gilboa Irises have deep purple or brownish flowers, but some rare individuals show pale yellow or golden blooms. These unusual forms are not common. The species is closely related to other irises in the region, but genetic research has shown it is a separate species.

What Gilboa Iris means

Chosen as the national flower of Palestine, the Gilboa Iris is a symbol of the region’s natural heritage. It is listed as vulnerable due to habitat loss and past over-collection. Nature reserves and legal protection have helped its survival. The flower appears in local campaigns and educational materials to raise awareness about conservation.
