One of the most captivating features of Iris tectorum are its leaves. Unlike many irises with upright, pointed foliage, Wall Iris boasts **basal fans of sword-shaped (ensiform) or lance-shaped leaves**. These beauties can grow up to 15-60 cm (6-24 inches) long and 1.5-5 cm (1-2 inches) wide. Imagine lush, **glossy green** blades gracefully arching outwards, forming a dense clump that creates a striking textural contrast with other plants in the garden. Adding to their charm, the leaves are prominently **ribbed**, giving them a sophisticated, almost pleated appearance. This ribbing not only adds visual interest but also helps strengthen the leaves, allowing them to withstand wind and rain. Another interesting aspect of Iris tectorum leaves is their **semi-evergreen** nature. In warmer climates, they may stay green throughout the winter, providing year-round visual interest. In colder regions, the leaves may turn brown or die back in winter, but the plant readily produces new growth in spring. While the dazzling blue flowers of Iris tectorum are a true showstopper, the architectural beauty of its leaves shouldn't be overlooked. These graceful blades provide a foundation for the blooms and add a touch of lush greenery to the garden throughout the season. Here are some additional interesting facts about Iris tectorum leaves: * **Growth habit:** The leaves arise from a creeping rhizome, forming spreading clumps of plants. * **Leaf color:** The leaves are typically yellowish-green or pale green, but some cultivars may have variegated foliage. * **Leaf texture:** The leaves are smooth and glossy with a pronounced midrib. * **Maintenance:** Iris tectorum leaves require minimal maintenance. Simply remove any dead or damaged leaves in early spring to encourage new growth. So, if you're looking for a perennial that offers both stunning flowers and beautiful foliage, Iris tectorum is a perfect choice. Its architectural leaves will add a touch of elegance to your garden year-round. Ref.: - https://gemini.google.com/
