Flower:

Flower is 3 to 4 inches across with 3 large petal-like sepals that hang down and 3 smaller upright petals. The lower sepals have a ring of reddish brown flecks near the base and are beardless. There are a few flowers at the end of each stalk.

Leaves:

Leaves are long and sword-like, about 1 inch wide and 3 to 4 feet long with a pointed tip. A group of leaves fans out from the base of the plant. The leaves are mostly longer than the flower stalk.

Fruit:

Fruit is an oblong, 3 angled capsule around 2 to 3 inches long and 1/3 to ½ as wide.

Notes:

Pale-yellow Iris is an invasive species in Minnesota, escaping cultivation and potentially forming large colonies along shores and in shallow waters. It is most easily identified by the bright yellow flowers, but when flowers are not present, it can be distinguished from our native blue Irises by the leaves, which have a prominent midvein, where both of our natives have a more obscure midvein, the leaves nearly flat in cross-section.
