Which is which?
Can you tell which part of this plant, Calla palustris, is the flower? Did you guess the white “petal”? That is called the spathe, a leaf-like bract that surrounds the cluster of flowers. The much tinier green and white flowers are held together on a spadix. If this plant looks familiar, it is related to the Calla lily that many people have sitting on their window sills. Funny enough, the Calla lily (Zantedeschia aethiopica) is not in the same genus as the plant shown above.
