Classroom Resources for Plant-Based Learning

Plant Family Tree

Our Plant Family Tree presents a selection of well-known plants arranged according to their evolutionary relatedness and age of diversification.The ancestors of plant families located on the tree's lowest and "inner" branches evolved earlier in the history of plants than those found on the upper and outermost branches. Plants located along a branch are more closely related to each other than to families on different branches.
