Amy Levy's poem opens by turning expectation upside down. In a London square, the country trees ought to be the healthy ones. Instead the plane-tree is "green" while "the other trees are brown," drooping and pining for the air they were meant to breathe. "Pine" is a small pun, since pines are trees, and it gives the grumbling trees a faint comic sadness. The plane-tree, meanwhile, "loves the town." The central idea is that a living thing can flourish in the place others reject, and that this flourishing comes from attention, not stubbornness.
The form is plain and neat. Each of the four stanzas alternates longer lines of four beats with shorter lines of three, a ballad-like pattern, and rhymes in an ABAB scheme: square/air, brown/town. Because the short lines carry the main claims, they land with a quiet click: "The other trees are brown," "The plane-tree loves the town," "And spread her shade below." The poem's simple music suits its argument. A tree that is content with its surroundings gets a poem with no strain or showiness in it.
The speaker watches from a "garret-pane," a high, small window, and the verb "mark" suggests careful, patient noticing. From there we see the tree's year in action verbs: she buds, blows, sheds and spreads. The most striking word is "recuperative." It is the longest and most clinical word in the poem, and it makes the shedding of bark sound like a form of healing. Plane trees are known for flaking bark, and here the habit becomes a way of renewing herself in sooty air. The tree is personified as "she" throughout, which makes her feel like a neighbour, not a symbol. The poem also doesn't stick to one season. The tree buds and spreads her shade while the others are already brown, as if she runs on a calendar of her own.
The third stanza shows how Levy handles the city's grime. Fog and smoke are the standard complaints about Victorian London, but here the breezes "play" and the "dun fog wraps her round about," as one might wrap a shawl around someone. Even the smoke only "curls grey," a verb that makes it almost decorative. "Dun," a dull brownish-grey, is an honest colour, and it is not romanticised. The poem never denies that the city is dingy. It lets the tree live inside that dinginess without being diminished. Whether the fog protects or smothers is left slightly open, and that ambiguity keeps the stanza from sounding like an advertisement.
The last stanza widens the poem. "Others the country take for choice, / And hold the town in scorn" could describe trees, but it sounds just as much like people, and the poem lets the two blur. The word "choice" matters. A rooted tree chooses nothing, yet the poem insists that she has "listened to the voice / On city breezes borne." We are never told what the voice says. Leaving it unspecified suggests that the city has something to say that only those who stay still and pay attention will hear. The speaker, perched in a garret and watching, seems to be doing the same listening. That identification is an inference from the poem's stance, not a stated fact, but it is hard to miss.
What makes the poem significant is this reversal. Poetry has often treated the countryside as the true home of nature and the town as its enemy. Levy keeps the green, the buds and the breezes, and moves them to a square with fog overhead. Her argument is that nature can be found wherever something is alive and responsive, and that scorn for the town may reveal more about the scorner than about the place. In sixteen short lines, the poem asks readers to look at what is flourishing in their own surroundings before they wish themselves elsewhere.
