With the coming of the winter season botanical interests are directed chiefly toward yuletide plants, one of which is the holly. The species most commonly used in wreaths and decorations is the English Holly (Ilex aquifolium L.); however, many people are unaware that a number of native holly species are found in eastern North America and two of them occur in Wisconsin. Unfortunately, the Wisconsin representatives are deciduous shrubs and not suitable for Christmas decorations. Although' of no value to us for the holiday season, their fruits are eaten by overwintering birds and squirrels, hence they may be considered as a winter treat for wildlife.
