Did you know?

The common name Adam-and-Eve orchid comes from the fact that old roots (Adam) give rise to new roots (Eve). The common name puttyroot is based on the historical use of the sticky substance found in the roots as a glue to mend pottery. You could say that this plant is a precursor to super glue.

State Ranking Justification

While this plant was apparently more common in the 1800s, today only three locations are known. This plant may face various threats, but the reasons for its decline are not well understood. There appears to be plenty of habitat available across a rather large portion of the state. While it seems unlikely that people would overlook an orchid, this is possible since the leaves are only visible from fall to spring.

Short-term Trends

Since 1950, only three populations have been observed and today only three still exist. These three populations have about 20-30 plants. While two populations are within protected landscapes, the trends might indicate broader threats that may one day lead to the loss of this plant from the New York flora.

Long-term Trends

Between 1850 and 1900 there were a minimum of 40 known populations. Between 1900 and 1950, the number of reported populations dropped to approximately 15. Since 1950, only three populations have been reported. The causes of this decline are unknown.

Conservation and Management


There are probably many influences that have lead to the sharp decline of this plant. These threats may include acid rain deposition, changes in soil chemistry, changes in the composition of soil fungal species, and deer herbivory.

Conservation Strategies and Management Practices

Provide a large undisturbed buffer around occurrences of this orchid. Monitor population numbers.

Research Needs

Research is needed to find the causes of the rapid decline of this species in the state.



This is an orchid of rich woods, often found near limestone outcrops or in calcareous talus. The moisture of the soil varies from mesic upland sites to damp low ground areas. Most of the woods are deciduous or mixed deciduous-evergreen (New York Natural Heritage Program 2005). Moist, deciduous, upland to swampy forests (Flora of North America 2002). Rare in moist, rich wooded slopes and bottomlands (Rhoads and Block 2000). Rich woods (Gleason & Cronquist 1991). Rich woods, both upland beech-maple and more swampy woods in low ground (Voss 1972). Rich woods (Fernald 1970).

New York State Distribution

Historically this orchid has been reported throughout the state, but today it is only known from three population from the Adirondack Foothills, Eastern Allegheny Plateau, and Great Lakes regions.

Global Distribution

This plant ranges from western New England west through southern Quebec, southern Ontario, Michigan, Wisconsin, and southeastern Minnestoa south to Arkansas, Tennessee, far northeastern Georgia, northwestern South Carolina, and the mountains of North Carolina.

Identification Comments

General Description

Puttyroot orchid spends the fall through the early spring as a solitary basal leaf that can be seen sticking slightly up at an angle from ground-level. The leaf is oval with a pointed tip and base, dark green with white stripes along the veins, and pleated. The underside is a purplish color. During May or June a green (with a few colorless bracts) flowering stem 1-2 feet tall is produced and the leaves wither. At the top of the stem 7-15 widely spaced flowers arise on stalks about as long as the flowers. The tan and green flaring sepals and forward-facing petals have showy purple tips. The lip is white with purple spots and a wavy edge. As the flowers age they tend to hang down.

Identifying Characteristics

The stems of this orchid arise from a globose corm and may reach a height of 50 cm. The solitary winter basal leaf forms late summer to fall and persists into spring and usually withers before flowering. The leaves are pleated with white strips paralleling the linear veination. The flowers are without a free spur, hence the generic name A-plectrum (without a plectrum or spur).

Best Life Stage for Proper Identification

This orchid may be identified by its winter basal leaf or by its flower. The winter leaf appears in the fall and persists until spring. A photograph of the leaf or images showing the overall stem growth plus close-ups of the flower should verify the identification of this plant. A description of the habitat may also prove helpful in confirming the identity.

Similar Species

Vegetative plants of Tipularia discolor may be confused with Aplectrum. Tipularia has leaves which are green to greenish-purple on top, purple underside, and are absent of any white striping or pleating. The leaves of Aplectrum are pleated and with numerous white stripes. In New York, Tipularia has only been observed in eastern Long Island and in the Rochester area. Aplectrum is not known from Long Island, so the only potential range overlap appears to be western New York.

Best Time to See

The winter basal leaf develops in late September and is visible early in the spring through April. The flowers develop early May to mid-June and fruits develop late June through September. The ideal survey time is late fall after most herbaceous plants have gone dormant for the winter and before too much snow falls. Surveys may also be conducted in the early spring when the leaves are still present, as well as during the months of May and June when this plant is likely to be in flower.
