Summary

Puccoon is a striking native perennial recognised by its narrow leaves and bright yellow trumpet-shaped flowers with distinctive fringed lobes. It is widespread across the Great Plains and the American Southwest, growing in prairies, desert uplands, juniper woodlands, and mountain habitats. Although various Indigenous peoples occasionally used the roots or leaves, modern evidence indicates the plant should not be considered a safe food because it contains toxic pyrrolizidine alkaloids and compounds that may affect fertility.


Physical Characteristics

 icon of manicon of flower
Lithospermum incisum is a PERENNIAL growing to 0.4 m (1ft 4in) by 0.3 m (1ft) at a medium rate.
See above for USDA hardiness. It is hardy to UK zone 4. It is in flower in June. The species is hermaphrodite (has both male and female organs) and is pollinated by Bees, insects.
It is noted for attracting wildlife.
Suitable for: light (sandy) and medium (loamy) soils and prefers well-drained soil. Suitable pH: neutral and basic (mildly alkaline) soils. It cannot grow in the shade. It prefers dry or moist soil and can tolerate drought.

Edible Uses

Edible Parts: Root
Edible Uses: Tea

Puccoon is an attractive and ecologically valuable native wildflower, but it falls well short as a food plant. Although historical accounts document occasional use of its roots and leaves, the combination of unpleasant flavour, poor food quality, liver-toxic pyrrolizidine alkaloids, and potential effects on fertility make it a species best appreciated for its botanical interest rather than its edible value[2-3]. Historical accounts record some Indigenous peoples eating the roots and occasionally consuming the leaves fresh. However, species in the Lithospermum genus contain pyrrolizidine alkaloids, compounds capable of causing liver damage. The roots have also been reported to possess contraceptive properties and may cause permanent infertility in both women and men. Because of these safety concerns, no part of the plant should be considered a safe wild food[2-3]. Edibility Rating: 1 out of 5 – Historical food use exists, but significant toxicity concerns mean this plant should be avoided. Taste and Preparation: Freshly dug roots are dark brown on the outside, with pale tan interiors and thin skins that peel easily. The roots are only weakly starchy but strongly acrid, with a burning sensation that intensifies as you eat more. Cooking does little to improve either the flavor or the pungency. The leaves are considerably milder than the roots. Fresh leaves have a pleasant, salad-like flavor despite their rough hairs, while the stems, flowers, and young shoot tips soften readily when cooked and produce a yellow-tinted broth. Even so, the edibility of the leaves is poorly documented, and because of the toxic compounds present within the genus, consumption is not advised. Seasonality (Phenology): Puccoon flowers from June through November. Roots may be collected whenever the plant can be positively identified, but this is discouraged because of safety concerns. Traditional Uses: Historical records indicate that the Thompson people of British Columbia ate the roots, while Frank Russell recorded that the Pima people consumed the leaves of various Lithospermum species. Far more commonly, species in this genus were valued as medicinal plants rather than food. Safety: Do not consume this plant. Lithospermum species contain pyrrolizidine alkaloids, which can damage the liver with repeated exposure. The roots have also been associated with contraceptive effects and possible permanent infertility in both women and men. While historical food use exists, the risks substantially outweigh any potential nutritional benefit [2-3]. Root - cooked[105, 161, 207, 212]. Eaten boiled or roasted[257]. The root has been used to make a tea[257].

Contraceptive  Kidney  Miscellany  Ophthalmic  Pectoral  Stomachic

The root has been chewed by some native North American Indian tribes as a treatment for colds[213]. The finely powdered leaves, root and stem have been rubbed on the body in the treatment of paralyzed limbs[257]. An infusion of the root has been used in the treatment of stomach aches and kidney problems[257]. The plant has been eaten as an oral contraceptive and also as a treatment for lung haemorrhages, coughs and colds[257]. A cold infusion of the pulverized root and seed has been used as an eyewash[257]. This plant was used as a medicine by various native North American Indian tribes and interest in the plant has revived recently as a possible source of modern drugs[212]. No more details are given.

The dried plant tops have been burnt as an incense[257]. A blue dye has been obtained from the roots[257]. A red dye is obtained from the roots[274]. It is quite possible that both colours can be obtained, depending on the mordant used[K]. The seeds have been used as beads[257].

Cultivation details

Puccoon prefers full sun and well-drained soils. It tolerates drought well and is adapted to dry, open environments. Habitat Found in prairies, desert uplands, open juniper woodlands, grasslands, and mountain slopes from Texas to North Dakota and westward across much of the interior western United States. USDA Hardiness Zones: USDA Zones 4–9. Growth Rate: Moderate. Plants emerge each spring from perennial taproots and develop slowly into compact flowering clumps. Mature Size: Typically 10–40 cm (4–16 in) tall. Cultivation: Puccoon is occasionally cultivated in native wildflower gardens for its unusually long, yellow trumpet flowers. It requires excellent drainage and full sun and performs best in dry, lean soils. Pollinators: The bright yellow tubular flowers attract native bees, butterflies, and other long-tongued pollinating insects adapted to reaching nectar deep within the corolla. Identification: Puccoon is an upright perennial arising from a taproot. It bears narrow, alternate leaves covered with coarse hairs and produces showy yellow trumpet-shaped flowers with five deeply fringed lobes that spread almost at right angles to the floral tube. The fruits consist of one to four hard, stone-like nutlets, giving rise to the common name "stoneseed." Similar Species: Puccoon can resemble other western members of the Lithospermum genus, including purple stoneseed (Lithospermum multiflorum) and mountain gromwell (Lithospermum ruderale). All share similar growth habits and should likewise be approached with caution because of the toxic compounds present within the genus. Requires a warm sunny position in a moderately fertile well-drained soil[1, 200]. Dislikes acid soils[1]. After producing large, conspicuous flowers in the spring, the plant produces lots of small very fertile cleistogamous flowers[274].

Can anyone please advise if Lithospermum (Heavenly Blue) should be pruned after flowering each year, or just left alone ?
