Cypripedium acaule

For example, Algonquin people, who form part of the larger cultural group known as the Anishinaabeg,[6] traditionally used C. acaule to treat menstrual disorders.

As C. acaule takes many years to go from seed to mature plant, the gathering of seed-bearing specimens is presently unsustainable.

The sepals and petals tend to be yellowish-brown to maroon with a large pouch that is usually some shade of pink but can be white to nearly magenta.

[3] POWO lists a dozen synonyms, one of which is Cypripedium acaule f. albiflora E.L.Rand & Redfield, a form with a white pouch and green petals.

Cypripedium acaule can be found in the eastern third of the United States, particularly in the Great Lakes region and the Northeast in New Hampshire and Maine, south along the Appalachians to Alabama.

[19][20] Within its geographic range, it can be found in a wide variety of environments, from coastal plains, to pine barrens, to mountaintops.

This is primarily due to the extra care that must be provided if the growing site is not naturally suitable for in-ground cultivation.

High quality peat moss or pine duff work well, and pH neutral perlite can be added to improve porosity.

Rainwater or distilled water mixed with 2 ounces (57 g) of vinegar per gallon will assure that a reliably high acidity is maintained in the growing medium.
