Boraginaceae (Borage Family)
Synonym(s): Batschia linearifolia, Lithospermum angustifolium, Lithospermum linearifolium, Lithospermum mandanense
USDA Symbol: LIIN2
One to several leafy stems, branched above on older plants, rise 6-16 in. high. Leaves are alternate, 2-4 inches long with rolled edges, larger near the base. Tubular, lemon yellow flowers with conspicuously fringed lobes are in clusters at the end of stems which are 6-12 inches long. They are trumpet-shaped with 5 petal-like lobes which open to 1 inch across, with crinkled margins. Very narrow leaves are less noticably hairy than other puccoons.
The genus name means stone seed, referring to the hard nutlets. This species produces few fruits from the showy flowers; instead, late in the season inconspicuous flowers that remain closed produce fruit in the lower leaf axils. There are several species in the West, one white-flowered, the rest with shorter, yellow corollas.

PropagationPropagation Material: Seeds
Description: Soak seeds in hot (135 degrees) water overnight, and plant immediately. Germination is unreliable. Propagation may be accomplished from 2-inch root cuttings. Treat cuttings with hormones and plant in fall. Mature plants may be divided.
Seed Collection: Late in summer, the plant produces smaller, almost invisible flowers which fertilize themselves without opening. It is from these late, hard-to-see flowers – not the showy yellow ones – that produce fertile seed. Inside each of four oblong nutlets is a bony, white seed.
Seed Treatment: Some references suggest stratification.
