Anchusa sempervirens

Scientific name: Anchusa sempervirens. Verified common name(s): evergreen bugloss (generalized common name within the genus Anchusa). Family: Boraginaceae. Genus: Anchusa. Taxonomic relationships: a member of the borage family (Boraginaceae), sharing typical family traits such as rough, hairy foliage and five-lobed corollas.

Form and size: A herbaceous perennial that typically forms a low to medium clump of upright to sprawling stems; plants may be semi-evergreen in mild climates. Flower characteristics: Flowers have a five-lobed corolla (commonly appearing as five distinct lobes) and are often bright blue to violet in color; individual blooms are tubular at the throat and open to a flat or slightly funnel-shaped face. Flowers are typically produced in coiled (scorpioid) cymes characteristic of the Boraginaceae. Leaf structure and arrangement: Leaves are alternate, lanceolate to oblong, and covered with coarse hairs, giving a rough texture. Lower leaves may form a basal rosette while stem leaves clasp or attenuate along flowering stems. Distinctive identifying features: Rough, hairy foliage combined with vivid blue, five-lobed flowers in coiled inflorescences; the name sempervirens and its tendency to retain foliage in mild climates can help distinguish it from some related species. Seasonal variation: Plants may be more herbaceous or partially evergreen depending on winter severity; flowering occurs seasonally when conditions are favorable.

General growing conditions: Often cultivated as an ornamental and commonly found escaped or naturalized in temperate, well-drained sites. Typically prefers full sun to partial shade and soils that are reasonably well drained. Ecological settings: Often encountered in gardens, rocky or disturbed sites, and other open, temperate habitats where it has been introduced. Geographic distribution: Recorded in the United States in California (CA), Maine (ME), Oregon (OR), and Washington (WA); occurrences in these states are commonly associated with cultivation or escape from cultivation rather than native populations.

Pollinators: Bright blue flowers commonly attract bees and other nectar-seeking insects; borage-family blooms are generally important for bee foraging. Wildlife interactions: Flowering stands may provide nectar resources for a variety of pollinators; rough foliage can deter some herbivores. Ecological niche: Functions as a nectar-producing herbaceous perennial in temperate garden and disturbed-site communities where it occurs.

Primarily cultivated as an ornamental for its vivid blue flowers. Some members of the Boraginaceae family are known to contain pyrrolizidine alkaloids and can be toxic; therefore caution is advised regarding ingestion by people or livestock, though specific toxicity reports for Anchusa sempervirens are not universally documented.

Conservation status: No widely recognized global-threat status is documented here. Interesting facts: The species epithet sempervirens means “evergreen,” reflecting its tendency to retain foliage in mild climates. The coiled (scorpioid) inflorescence and rough, hairy leaves are classic, identifiable traits of many borage-family species.
