It is a rhizomatous perennial, from the shrublands and mountainsides of Palestine, in Samaria and Israel, in the Gilboa mountain. It has smooth, linear or lanceolate, greyish-green leaves. Long slender stem and in Spring, (between March and April) large, fragrant flowers in shades of deep purple, violet, purple, brownish purple or dusky lilac veining or speckling over a pale ground.
