Noteworthy Characteristics

Iris graminea is a beardless dwarf spuria iris that grows from a rhizome to 8-18” tall. It is native from Spain to Russia and throughout the Caucasus. In the wild, it comes in a variety of different forms depending on geographic location. Plants from central Europe generally have grass like leaves with flower spikes that are somewhat hidden by the foliage. Each flower spike bears two flowers (to 3” long) which have purple standards, purple style branches and violet falls with violet-veined, yellowish-white hafts. Flowers have a fruity aroma somewhat reminiscent of ripe plums, hence the sometimes used common names for this plant of plum iris or plum-scented iris. Flowers bloom in June. Grassy foliage clump may elongate after bloom. Graminea means grass in obvious reference to the grass-like clump of leaves.

Problems

No serious insect or disease problems. Crown rot is an infrequently occurring disease problem. Susceptible to certain viruses.

Garden Uses

Best grouped in sunny areas of rock gardens or borders fronts. Fragrant cut flower for a small vase.
