Plants grow in high understory shade with dappled to indirect sunlight. The only female (fruiting) plants were found in areas along the creek where soils are moist to saturated. Numerous male specimens were found in the areas described above. Soils: Soils found in the areas where this collection was made are comprised primarily of Baile silt loam (Ba), Hatboro silt loam (Ha), and Glenelg silt loam, 8 to 15 percent slopes (GgC). Baile silt loam consists of very deep, poorly drained, moderately low to moderately high saturated hydraulic conductivity, soils on upland depressions and footslopes that were formed in local alluvium over residuum from acid crystalline rocks, chiefly mica schist and granitized schist and gneiss; slope ranges from 0 to 8 percent. Hatboro silt loam consists of very deep and poorly drained soils formed in deposited alluvium derived from metamorphic and crystalline rock. They are on flood plains. Slopes range from 0 to 3 percent. Glenelg silt loam, 8 to 15 percent slopes consists of very deep, well drained soils formed in residuum weathered from micaceous schist on uplands of the Blue Ridge and the Northern Piedmont. This soil is undifferentiated, mostly poorly drained sandy bottomland soils intermingled with decomposing organic litter and eroded silts and clays due to erosion.

Plants are growing in high understory shade with very little direct sun during most of the day. The remnant woodlands exist mostly along the steep slopes, wetlands and seeps of seasonal and year-round creeks flowing into the Middle Branch White Clay Creek. The woodlands are bordered by numerous housing developments and land converted to meadows; hence there is significant first order edge that is heavily impacted by invasive plant intrusion. Soils: Soils are classified as Glenelg silt loam, 8 to 15% slopes (GgC); this series consists of very deep, well drained soils formed in residuum weathered from micaceous schist on uplands of the Blue Ridge and the Northern Piedmont.
