Iris wattii
Bamboo Iris (Iris wattii) is an elegant and colourful plant that adds beauty to any garden. It is an evergreen species native to the Himalayas and parts of East Asia, where it grows in dense clumps. The stems of these irises are slender and wire-like, resembling those of bamboo, giving the plant its name. Its stunning flowers range in colour from deep yellow and bronzy-orange to vivid purple and red, and appear abundantly during the spring and summer. To keep these plants blooming every year, it is important to provide them with moisture-rich soils, adequate sunlight, and regular pruning.
