Hydrastis canadensis L.

Habitat [-]
Goldenseal colonies are found at the bottom or mid-slopes of rich woodlands, often near streams. Sometimes the slopes are deeply dissected by runoff or they may consist of limestone talus and cliffs. The forests are usually mature with old logs and an open understory with a diverse Spring wildflower flora. The underlying rock is usually limestone and the soils are rich in organic matter, sometimes with springs emanating from the slopes. (New York Natural Heritage Program 2007). Deep rich woods (Fernald 1970). Deep rich woods (Gleason 1952).

Associated Ecological Communities [-]
  • Calcareous talus slope woodland
    An open or closed canopy community that occurs on talus slopes composed of calcareous bedrock such as limestone or dolomite. The soils are usually moist and loamy; there may be numerous rock outcrops.
  • Floodplain forest
    A hardwood forest that occurs on mineral soils on low terraces of river floodplains and river deltas. These sites are characterized by their flood regime; low areas are annually flooded in spring, and high areas are flooded irregularly.
  • Limestone woodland
    A woodland that occurs on shallow soils over limestone bedrock in non-alvar settings, and usually includes numerous rock outcrops. There are usually several codominant trees, although one species may become dominant in any one stand.
  • Maple-basswood rich mesic forest
    A species rich hardwood forest that typically occurs on well-drained, moist soils of circumneutral pH. Rich herbs are predominant in the ground layer and are usually correlated with calcareous bedrock, although bedrock does not have to be exposed. The dominant trees are sugar maple, basswood, and white ash.
  • Oak-tulip tree forest
    A hardwood forest that occurs on moist, well-drained sites in southeastern New York. The dominant trees include a mixture of five or more of the following: red oak, tulip tree, American beech, black birch, red maple, scarlet oak, black oak, and white oak.
