*ARBORVITAE AND THEIR LOOKALIKES: Identification and Natural History
FREE. Advance registration required.
What is the difference between true Arborvitae (Thuja spp.) and false Arborvitae (Chamaecyparis spp.)? What is the difference between false cedars (Thuja spp. and Chamaecyparis spp.) and true cedars (Cedrus spp.)? In this webinar, Elizabeth Price will disentangle the confusing naming conventions for these groups of conifers. She will also highlight foliage and cone characteristics for quickly differentiating among these notoriously difficult-to-identify conifers.
Price will also discuss the fascinating natural history of these plants, including: Why Arborvitae were named the “tree of life” or “Arbre de Vie” by early explorers and why a warming climate is causing Alaska-cedars to die of the cold.
