Moist open land is the habitat of the Lily-leaved Twayblade (Liparis lilifolia).
Specifically, this wild orchid handles moist soils. It therefore is able to survive in floodplains and along stream banks. But it also may grow up and down moist wooded slopes.
Moist lowlands is the habitat of the Southern Twayblade (Listera australis).Specifically, this wild orchid favors moist soils. For example, it fluorishes in bogs. But it also thrives in moist woodlands, pine barrens and thickets.
Moist woodlands is the habitat of the Appalachian Twayblade (Listera smallii).Specifically, this wild orchid favors moist, nutrient rich soils. It therefore flourishes in damp mountain woodlands. But it also thrives in bogs and near thickets.
Moist open land is the habitat of the Large Twayblade (Liparis lilifolia).Specifically, this wild orchid favors moist soils. It finds the moisture and nutrient levels that it seeks in floodplains and along stream banks. But it also may be found on moist wooded slopes.
Acidic moist land is the habitat of the Yellow Twayblade (Liparis loeselii).Specifically, this wild orchid favors acidic soils that meet its moisture and nutrient needs. It finds these needs met in moist slopes and thickets as well as wet woods. It also finds them in bogs and swamps.
