Trachystemon orientale

Trachystemon orientale, commonly known as Abraham-Isaac-Jacob or early-flowering borage, is a perennial herb of the family Boraginaceae. Native to eastern Europe, it is frequently grown as an ornamental for its early blue-violet flowers and large leaves. It quickly spreads to provide a dense groundcover. Trachystemon is derived from the Greek "trachys", meaning rough, and "stemon", a stamen. The specific epithet, "orientalis" means eastern or from the orient, and is a reference to the native distribution of this species. Trachystemon orientalis is endemic to southeastern Europe and western Asia.[2]

The name can also refer to several related plants, such as species of Pulmonaria.
