Maianthemum racemosum, the treacleberry, feathery false lily of the valley, [3] false Solomon's seal, Solomon's plume [4] [5] or false spikenard, is a species of flowering plant native to North America. It is a common, widespread plant with numerous common names and synonyms, known from every US state except Hawaii, and from every Canadian province and territory (except Nunavut and the Yukon), as well as from Mexico. [5]
It is a woodland herbaceous perennial plant growing to 50–90 centimetres (20–35 inches) tall, with 7–12 alternate, oblong-lanceolate leaves 7–15 cm (2+3⁄4–6 in) long and 3–6 cm (1+1⁄8–2+3⁄8 in) broad. The leaf bases are rounded to clasping or tapered, sometimes with a short petiole. The leaf tips are pointed to long-tipped.
Seven to 250 small flowers are produced on a 10–15 cm (4–6 in) panicle that has well-developed branches. Each flower has six white tepals 3–6 millimetres (1⁄8–1⁄4 in) long and is set on a short pedicel usually less than 1 mm long. Blooming is mid-spring with fruiting by early summer. The plants produce fruits that are rounded to 3-lobed and green with copper spots when young, turning red in late summer. [5]
It spreads by cylindrical rhizomes up to 0.3 metres (1 ft) long with scattered roots. [5]
M. racemosum closely resembles members of the genus Veratrum , a highly toxic group of plants to which it is distantly related, as well as baneberry. [6]
The Flora of North America recognizes two subspecies: amplexicaule (Nuttall) LaFrankie and racemosum. [2] [5] They are geographically separated, with subsp. amplexicaule a western subspecies and subsp. racemosum found in the east, with some overlap in the central states. The western plants (subsp. amplexicaule) have erect stems and leaves with a clasping, rounded base and upper leaves with tips with short points. The eastern subspecies (subsp. racemosum) tends to have arching stems, leaves with a short petiole and upper leaf-tips with an extended point 12–25 mm (1⁄2–1 in) long. [5] Phylogenetic analyses however show there to be molecular differences and those differences, combined with the geographical separation and morphological differences suggest that these should be considered separate species: M. amplexicaule (Nutt.) W.A. Weber for the western species and M. racemosum (Linnaeus) Link for the eastern. [7]
The Latin specific epithet racemosum means "with flowers that appear in racemes", [8] which can cause confusion as the inflorescence is a panicle; it is the individual branches of the panicle that have flowers arranged in a raceme.
The species is widespread, found in all Canadian provinces and territories except the Yukon and Nunavut, all US states except Hawaii, and in Northern Mexico. Subsp. amplexicaule has been found in western Canada in Alta, B.C., N.W.T., Sask.; and in the western US in Alaska, Ariz., Calif., Colo., Idaho, Mont., Nev., N.Mex., N.Dak., Oreg., S.Dak., Tex., Utah, Wash., Wyo. [5] Also found in Mexico, in Chihuahua, Coahuila and Veracruz. [1] The eastern subspecies (subsp. racemosum) is found in Canada from Manitoba east, and in all eastern US states. Both subspecies are found in the Dakotas and in Texas. [5]
The plant grows in habitats in North America up to elevations of 2,743 m (9,000 ft). The most robust and profuse occurrences of this plant are typically found in partial shade and deep, moist, soft soils. In the western part of North America an example typical habitat would be in a shaded ravine or riparian corridor with common understory associates of Dryopteris arguta , Trillium ovatum and Adiantum jordanii . [9]
The plant, like the closely related Polygonatum (Solomon's seal), is suitable for cultivation in moist, humus-rich soil in a woodland setting or in dappled shade. [10] It has gained the Royal Horticultural Society's Award of Garden Merit. [11] [12]
Because it resembles plants of the highly toxic Veratrum genus, [6] this species should not be consumed unless identification is positive. [13] The plant becomes fibrous and bitter after it completes flowering and seed-setting, but the tender young shoots can be stripped of their leaves, simmered in water and eaten. Their delicate flavor is somewhat reminiscent of asparagus. The ripe fruits are edible raw or cooked [14] but may be poor in taste. [15] They can be laxative if consumed in large quantities.
Ojibwa harvested the roots of this plant and cooked them in lye water overnight to remove the bitterness and neutralize their strong laxative qualities. Native Americans boiled the roots to make tea for medicinal purposes, including to treat rheumatism, kidney issues, and wounds and back injuries. [15]
Polygonatum, also known as King Solomon's-seal or Solomon's seal, is a genus of flowering plants. In the APG III classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae. It has also been classified in the former family Convallariaceae and, like many lilioid monocots, was formerly classified in the lily family, Liliaceae. The genus is distributed throughout the temperate Northern Hemisphere. Most of the approximately 63 species occur in Asia, with 20 endemic to China.
Primula vulgaris, the common primrose, is a species of flowering plant in the family Primulaceae, native to western and southern Europe, northwest Africa, and parts of southwest Asia. The common name is primrose, or occasionally common primrose or English primrose to distinguish it from other Primula species also called primroses. None of these are closely related to the evening primroses.
Maianthemum includes the former genus Smilacina and is a genus of perennial herbaceous flowering plants with fleshy, persistent rhizomes. It is widespread across much of North America, Europe and Asia, and may be terrestrial, aquatic or epiphytic. It is characterized by simple, unbranched stems that are upright, leaning or hanging down and have 2–17 foliage leaves. Leaves are simple and may clasp the stem or be short-petiolate. The inflorescence is terminal and either a panicle or a raceme with few to many pedicelate flowers. Most species have 6 tepals and 6 stamens; a few have parts in 4s. Tepals are distinct in most species and all of similar size. Flowers are spreading, cup-shaped or bell-shaped and usually white, but lavender to red or green in some species. Fruits are rounded to lobed berries containing few to several seeds.
Maianthemum canadense is an understory perennial flowering plant, native to Canada and the northeastern United States, from Yukon and British Columbia east to Newfoundland, into St. Pierre and Miquelon. It can be found growing in both coniferous and deciduous forests. The plant appears in two forms, either as a single leaf rising from the ground with no fruiting structures or as a flowering/fruiting stem with 2-3 leaves. Flowering shoots have clusters of 12–25 starry-shaped, white flowers held above the leaves.
Maianthemum trifolium is a species of flowering plant that is associated with extremely wet environments and is native to Canada and the northeastern United States as well as St. Pierre and Miquelon and Asia (Siberia).

Symphyotrichum lanceolatum is a species of flowering plant in the family Asteraceae native to North America. Common names include panicled aster, lance-leaved aster, and white panicled aster. It is a perennial, herbaceous plant that may reach 1.5 meters tall or more, sometimes approaching 2 m. The lance-shaped leaves are generally hairless but may feel slightly rough to the touch on the top because of tiny bristles. The flowers grow in clusters and branch in panicles. They have 16–50 white ray florets that are up to 14 millimeters long and sometimes tinged pink or purple. The flower centers consist of disk florets that begin as yellow and become purple as they mature.
