Addressed to a "Fruitful Plant," this is a plea for someone or something to stay close, not just in good times but through every stage of decline. The speaker asks for company until the leaves turn yellow, until they fall one by one, and even until rot appears. Nothing about aging is hidden or softened. Yet the speaker doesn't treat these changes as reasons to leave. They are simply part of what must be waited through.
The final lines shift the focus. The plant will bear fruit "from the seeds I planted," which suggests the speaker has invested care and hope in this relationship. The plant could be a loved one, a child, or a project; the poem leaves that open. The mood is tender and patient, with a quiet insistence underneath. The image of leaves falling "slower than a feather" slows the poem down, making the decline feel gentle rather than frightening. Love here means staying until the work has paid off.
