Bokhara Iris

Iris bucharica | Also known as: Flag, Sword Lily, Iris | Rating: 0 votes | Print / Pdf

Known for its fantastically delicate flowers, as intricate and elegant as a Tolstoy novel.

It may be small, but Iris bucharica is one of the most captivating garden plants imaginable. Its glossy, lance-shaped, mid-green leaves are slender, but its flower is as elegant and intricate as it is beautiful. Commonly called the Bokhara Iris, these flowers feature delicate white petals with yellow falls that turn downwards, away from the flower centre. The overall image is hugely impressive, and with all-yellow cultivars available, can be even more so. As a clump-forming deciduous flowering plant, the Bokhara Iris is ideal as groundcover, as well as garden edging and in rockeries. It thrives in slightly alkaline, well-drained soil but requires a lot of sun to bloom fully.
