Lanceleaf Figwort
scrophularia lanceolata
The Lanceleaf Figwort (Scrophularia lanceolata) is an intriguing native perennial herb of North America, prized by wildlife and native plant enthusiasts alike. Reaching heights of up to 2.5 meters, this tall, upright wildflower features a distinctive square stem and opposite, sharply toothed leaves. While its tiny, cup-shaped flowers might seem inconspicuous to the casual passerby, they are absolute powerhouses of nectar production, acting as a vital fuel station for a diverse array of insects, particularly predatory wasps. Historically valued in traditional herbal medicine, this species thrives in transitional habitats like forest edges and open meadows. It plays an essential role in local ecosystems by supporting beneficial predatory insects that control pest populations.
Habitat: Typically found in open woodlands, forest edges, thickets, fields, and along disturbed roadsides.
Appearance
This tall, erect perennial stands 100 to 250 cm high, featuring sharply four-angled, grooved square stems. Its leaves are oppositely arranged, lance-shaped, and display prominent, sharp, double-toothed margins. The flowering structure is a narrow, elongated panicle covered in small, 1-cm long, urn-shaped flowers that are greenish-brown or dull red in color.

Interesting facts
Its scientific name Scrophularia refers to its traditional use in treating scrofula, a historical form of tuberculosis affecting the neck.
The name Figwort originates from the historical belief that the plant could heal a medical condition known as 'figs' (hemorrhoids).
Unlike most garden flowers that court bees, this species has evolved a strong evolutionary relationship with predatory wasps.
Special abilities
Wasp-Attracting Nectar
Produces abundant, easily accessible sucrose-rich nectar tailored specifically to attract and reward predatory wasps for pollination.
Square-Stem Support
Possesses a rigid, four-angled stem reinforced with collenchyma tissues that allow the plant to stand tall without wood.
Chemical Herbivore Defense
Synthesizes bitter iridoid glycosides throughout its foliage to deter grazing mammals and generalist insect pests.
