Do you know the differences between pines, firs, and spruces?  How about arborvitae, junipers, cedars, and false-cedars?  Some of these are easily distinguishable, while others require close observation of needle patterns and a deeper understanding of reproductive structures.  By the end of this session with Dr. Richard L. Bitner, you will have a clearer understanding of conifers.  Dress in layers so that you are comfortable both in the classroom as well outdoors among the Arnold Arboretum’s outstanding conifer collection.  The lecture/tour will be held Saturday, October 30, from 9 – 2, and will begin in the Hunnewell Building of the Arnold Arboretum.  The fee ($70 for members of the Arboretum or the Wellesley College Friends of Horticulture, $80 for non-members) includes a copy of Dr. Bitner’s book Timber Press Pocket Guide to Conifers.
