Iris juncea (commonly called the rush iris) is a smooth-bulbed bulbous iris species. The name is derived from 'juncea' from the Greek word meaning 'rush-like'.[1]

It was first described by Jean Louis Marie Poiret in 1871.[2] It was then illustrated in Curtis's Botanical Magazine in 1898.[3]

Its flowers are light yellow[4] and fragrant. Normally 2 per stem in summer.[5] It flowers between June and July.[3]

It grows to a height of between 1 and 2 feet.[6] The 3mm wide leaves appear in the autumn and then fade before flowering.[5]

The bulb is reddish-brown in colour.[3]

It can be found in (Algeria and Tunisia) in North Africa,[7] Southern Spain and Sicily.[5]
