Soil type preference: Phoradendron Leucarpum prefers sandy (light), loam (medium) and clay (heavy) soil. The preferred pH of the soil is acid, neutral and alkaline. However, the Mistletoe requires moist soil to grown in.

Habitat: Woodland, Multicolored Shade, Shady Edge. Phoradendron Leucarpum grows as a parasite usually on Acer rubrum and Nyssa spp but may also grow on shrubs. The Mistletoe usually grows on light woodland or no shade.

BiomesThe Phoradendron Leucarpum can exist in any kin of biomes. It can adapt to any ecosystem but undisturbed by human density, Phoradendron Leucarpum is found in Temperate Deciduous Fores, because one of the Characteristic of the Temperate Deciduous Forest is hardwood trees, and the Phoradendron Leucarpum which are parasitic plants, usually grows on high branches of the hardwood tree.

Phoradendron Leucarpum is found in abundant in tropical dryfaorest: savanna as well. In savanna the conditions such as solar incidence, host trees provide an ideal for the mistletoe growth.

However, Phoradendron Leucarpum is least concentrated in the Tropical rain forest because the Mistletoes need to have lower water potentials than their host plants to ensure the flow of water and nutrients moving through the haustorial connection. This is achieved by maintaining higher transpiration rates than that of their host plants. However, dense, dark condition of tropical Rainforest will not provide the accurate condition for Phoradendron Leucarpum.

Photosynthetic pathway: Phoradendron Leucarpum are semi-parasitic hence, the mistletoe gets some of its carbon and other nutrients from the host xylem. However, they have oval shaped, evergreen leaves so they do perform photosynthesis through out the year. Phoradendron Leucarpum has not been speciafically mentioned, but they probably perform C4  photosynthetic, firstly because they prefer dry ecosystem, and they grow only to certain height, so under such condition C4 photosynthesis would be preffered.
