Iris lutescens, commonly known as Crimean Iris, is a perennial herb native to the Mediterranean region, specifically to the open woodlands and rocky hillsides of Northeast Spain, Southern France, and Italy. It typically grows up to 12 inches tall and is characterized by its broad, sword-like leaves that are about 1 inch wide. The Crimean Iris produces showy yellow or violet flowers in the spring (March–April), which are highly valued for their beauty. The plant forms clumps through its rhizomatous growth habit, allowing it to spread gradually over time.

The Crimean Iris is appreciated for its hardiness, withstanding temperatures down to -20°C or less, and its drought tolerance during the summer dormant period. It is often used in rock gardens, borders, and as a ground cover due to its low maintenance and ability to thrive in slightly acidic, well-drained soils. In cultivation, it requires full sun to flourish and is recognized for its ornamental value, having received the Royal Horticultural Society’s Award of Garden Merit. Gardeners should be aware that while generally disease-free, the plant can suffer from iris borer and rhizome rot if conditions are too wet.CC BY-SA 4.0
