Paterson’s Curse

Echium plantagineum

Alternative Name(s): Salvation Jane

Family: Boraginaceae.

Form: Herb

Origin: Native of the Mediterranean region across to Portugal.

Flowers/Seedhead: To 3 cm long. Flowers all year but mainly late winter to early summer.

Description: Erect annual herb to 60 (rarely to 150) cm high. Stems one to several. Stems and leaves hairy with coarse hairs and sometimes shorter soft hairs. Leaves oval to lanceolate; basal leaves, in a rosette, to 20 (rarely to 30) cm long, with a short stalk; stem leaves reducing in size towards flowers.

Distinguishing features: Distinguished by leaves with spreading hairs having an enlarged base; flowers in caterpillar-like curved spikes; funnel-shaped flowers, usually purple but also blue or pink, less often white, unevenly lobed; stamens with filaments much longer than anthers, 2 stamens longer than the others and projecting past the flower tube; fruit consisting of 4 tuberculate three-sided nutlets (although some may not develop).

Dispersal: Spread by seed. Long distance spread often via fodder.

Confused With: Vipers Bugloss, Echium vulgare, which has 4 stamens projecting past flower tube (as opposed to 2 in Paterson’s Curse).

Notes: Initially introduced as an ornamental. Poisoning of sheep after years of grazing has been recorded; poisonous to pigs and horses. Crowds out more useful pasture species. Considered to be useful for build up of bee numbers early in the honey production season. Biological control agents have been released for control of this species.
