The speaker is talking to someone who is gone, and the beauty of the afternoon only makes that absence sharper. White phlox and hydrangeas are still blooming under a warm sun, but she knows they will drop and stain before the person returns. Because of that, she cannot enjoy them. Without the absent person, the garden no longer feels like a garden; color and light drain out of it. What remains is empty space stretching ahead, and she moves through it bent and unseeing. The poem ends with her listening for the first faint rustle of withered leaves, a sound that belongs more to loss and waiting than to life. The mood is quiet, sorrowful, and suspended, as if the speaker is caught between the present afternoon and the long emptiness to come.
Left Behind — Summary
White phlox and white hydrangeas. High, thin clouds, A low, warm sun. So it is this afternoon. But the phlox will be a drift of petals. And the hydrangeas stained and fallen Before you come again.
I cannot look at the flowers, Nor the lifting leaves of the trees. Without you, there is no garden, No bright colours. No shining leaves.
There is only space, Stretching endlessly forward — And I walk, bent, unseeing.
Waiting to catch the first faint scuffle Of withered leaves.
