This native semi-parasite flourishes on Limes, Poplars, Hawthorns, Maples, Mountain Ashes, Peaches, Robinias, and Apple trees, but is not encouraged in British orchards. Vast quantities of the forked stems, green-yellow foliage, and sticky whitish berries find their way to market about Christmastime, but the supplies chiefly come from the Continent. Beyond a certain amount of crude sap absorbed by the roots, which penetrate the tissues, the Mistletoe does but little harm to the host plant, as its leaves perform the work of assimilation and elaboration of food. Ripe seeds should be inserted in slits in the bark to secure a supply in the course of a few years.
