In the first stanza of "Our Casuarina Tree," Toru Dutt describes the "crimson clusters" of flowers that hang on the bough of the tree where the birds and the bees gather all day. This description is a form of zeugma, with the birds and bees yoked together as a symbol of life. In reality, the bees would be specifically attracted by the flowers, which they could pollinate. The birds might simply be looking for a convenient place to perch. However, their combined presence in the poem adds to the symbolism of the tree as a cynosure, a uniquely attractive object that draws all life towards it.

A tree is something that lives and grows, but its growth is imperceptible and its life is not immediately apparent to the observer. The poet adds life to the tree by various means, most importantly by showing how it lives in her memory and remains central to her existence even when she is far away. Before this, however, she describes not only the colorful flowers, but the birds and the bees, which add not only color and movement, but also sound. The tree and the garden in which it stands are therefore united with the rest of nature in "one sweet song."
