Lithospermum incisum

Lithospermum incisum1

Lithospermum incisum, commonly known as the fringed puccoon or narrowleaf stoneseed, is a species of flowering plant in the borage family (Boraginaceae). It is native to North America, where it is found in a variety of habitats from Canada through the central and eastern United States. This perennial herb is notable for its bright yellow flowers and its ability to thrive in both prairie and woodland settings.

Description

Lithospermum incisum is a perennial herb that reaches heights of 30 to 60 cm. Its leaves are narrow and lanceolate, with the entire plant covered in fine hairs. The plant blooms in late spring to early summer, producing clusters of bright yellow, tubular flowers. Each flower is 1.5 to 2.5 cm in length, with five distinct lobes that are slightly fringed at the edges, giving the plant its common name. The fruit of Lithospermum incisum is a small, white, nutlet that is hard and stone-like.

Habitat and Distribution

The fringed puccoon is adaptable to a range of habitats, including prairies, open woodlands, and roadsides. It prefers well-drained soils and can be found at elevations from sea level to over 2,000 meters. Its distribution spans from the southern regions of Canada, through the central United States, and into the northern parts of Mexico.

Ecology

Lithospermum incisum plays a role in the ecosystem by providing nectar for pollinators. Bees, particularly native species, are the primary pollinators of this plant, although it may also attract butterflies and other insects. The plant's seeds are consumed by various small mammals and birds.

Conservation

While Lithospermum incisum is not currently listed as endangered or threatened, its habitat is subject to the usual pressures of development, agriculture, and invasive species. Conservation efforts focus on habitat preservation and the management of invasive species to ensure the survival of this and other native plants.

Cultivation

Lithospermum incisum is occasionally cultivated for its ornamental value. It requires full sun to partial shade and well-drained soil. Once established, it is drought tolerant, making it a suitable choice for xeriscaping or naturalized areas. The plant can be propagated by seed or division in the fall.
