Foraging and Harvesting Solomon’s Seal
A Practical Guide
Solomon’s Seal (Polygonatum biflorum) is a perennial plant known for its arching stems and elegant, hanging flowers. As it matures, it produces bluish-black berries following the bloom of small, white flowers. This plant is traditionally valued not just for its ornamental qualities but also for its potential medicinal uses. Foragers seek out this woodland native for both its edible shoots and rhizomes, which emerge in the spring. Due to its popularity, it's important to emphasize sustainable harvesting practices, ensuring that enough of the plant remains to continue its lifecycle and proliferate for future seasons.
Identifying Solomon's Seal accurately is crucial, as it has look-alikes, such as false Solomon’s Seal (Maianthemum racemosum), which differs in the placement and structure of flowers and fruit. Foragers typically harvest Solomon's Seal in late spring when the shoots are young and tender, before the plant has fully flowered. The rhizomes are harvested later in the growing season once the plant has gone dormant. These underground parts are thick, usually around one inch in diameter, and are reputed for their therapeutic value. Growing Solomon's Seal in a home garden or shade garden offers a sustainable alternative to wild harvesting, allowing personal use without impacting natural populations.

Solomon's Seal refers to plants in the Polygonatum genus, which are part of the Asparagaceae family. Notably, the genus includes varieties like Polygonatum biflorum and Polygonatum odoratum.
These plants are characterized by their arching stems and rows of tubular flowers, which typically dangle beneath the leaves. They are perennial herbs, meaning they grow back each year from the same root system. The leaves of Solomon's Seal are alternate, and the plants produce berries that transition from green to dark blue or black at maturity.
Here is a brief profile:
Family: Asparagaceae
Genus: Polygonatum
Common species:
Polygonatum biflorum (Common Solomon’s Seal)
Polygonatum odoratum (Fragrant Solomon’s Seal)
Growth habit: Arching stems with alternate leaves
Flower type: Tubular, usually white or cream
The plant is native to various parts of the world, including North America and several continents across the globe. Solomon's Seal is often found in woodland areas, thriving in the shade.
Different species within the genus Polygonatum are known commonly as "Solomon's Seal." Polygonatum spp. vary slightly in their appearance and habitat preferences, but all share similar growing conditions and botanical characteristics.
These plants have been used traditionally for culinary and medicinal purposes, though one should be versed in proper identification techniques to ensure accurate recognition, as there are look-alike plants such as False Solomon's Seal. Foraging Solomon's Seal requires a sustainable approach to preserve populations, as they can be sensitive to overharvesting.
Identification of the Plant
Successfully identifying Solomon's Seal is key for both gardening enthusiasts and foragers. This section details the plant's distinct features, which are crucial for accurate identification and distinguishing it from similar species.
Characteristics of Stems and Leaves
Solomon's Seal, known botanically as Polygonatum, typically features arching stems and alternately arranged leaves. The stems are usually green, but can also have a bluish-green hue. Leaves of Solomon’s Seal are elongated, ovate to lance-shaped, and may come in variegated forms, especially in cultivated varieties.
Flowering and Fruiting Features
The plant is characterized by its small, bell-shaped white flowers, often tipped with green, which dangle from the leaf axils in spring. The flowers usually grow in clusters of one to several blooms. After the flowering period, the plant produces berries that can be blue-black or red when mature, and these contain seeds which are primarily dispersed by wildlife.
Distinguishing Between Species
Identifying Polygonatum biflorum vs. its close relative, Polygonatum odoratum, often depends on subtle differences like flower arrangement and scent. However, differentiating either from the False Solomon's Seal, Maianthemum racemosum, is easier, as the latter has its flowers—and later, red berries—at the tip of the stem rather than along the stem. It's also important to note that all parts of the True Solomon's Seal are edible, while the False Solomon's Seal is not considered an edible plant.
Habitat and Growing Conditions
Solomon's Seal thrives in conditions that reflect its native woodland habitat, requiring specific considerations in soil and light, as well as proper techniques for propagation to maintain healthy growth.
