Of the thousands of trees that are sold in Philadelphia, most are Black Spruce from the mountains of north-east Pennsylvania. There are a few Pinus rigida, or Pitch Pine, with an occasional Red Cedar from New Jersey. From the refuse of country nurseries there are a few Norway Spruce, White Pine, and Balsam Fir. The latter wholesaled at from $20 to $25 per 100. They ran from 7 to 10 feet high. The native trees brought about $40, and the very large ones about $70. The retail prices are about double, so as to compensate the risk of "stock left on hand".
The wreathing is made of Holly (Ilex opaca), the berries of the deciduous Holly or Black Alder (Ilex verticillata) doing duty for the regular berries of the evergreen Holly. " Pine wreathing " is Lycopodium dendroideum - and "crowfoot wreathing," which is Lycopodium complanatum - these used to be called Ground Pine, and (the latter) festoon Ground Pine, but common names change every year or two. Then the Laurel (Kalmia lati-folia) and the Teaberry (Gaultheria procumbens) complete the list of wreathing materials. Mistletoe branches are growing in favor, and a quantity with pure white berries, coming in barrels from Europe, met with ready sales.
