Description
editSisyrinchium montanum is a herbaceous perennial plant that grows in clumps between 10 and 50 cm (4 and 20 in) tall. Its stems have wings with entire to finely toothed margins. The leaves and stem are slender, 3 mm (1⁄8 in) broad, green or brownish, with sharp edges and a fine point.
The flowers are produced in a small cyme of two to five together emerging from a spathe, each flower about 2 cm (3⁄4 in) diameter, with six purplish tepals with a yellowish base and yellow stamens. The fruit is a capsule 4.5–6 mm (0.18–0.24 in) long, containing numerous small black seeds.[7][8]
