A yucca speaks, and the first thing it tells us is that it is sharp. "Aboveground, I am all blade" is a boast, and the rest of the stanza keeps it up. The plant sheds filaments "to keep / my edges keen," goes "months / & months" without water, and sends its connections deep into the sandstone. Everything here is about self-sufficiency. Even the word "Aboveground" admits there is a hidden half, a root life we can't see, and that half is described with quiet pride.
Then comes the "But." The second stanza turns on something the speaker cannot explain: "when I blossom, / nothing happens." Readers who know yuccas may supply the missing piece, since the plant is famous for depending on a particular moth to pollinate it. The poem never names the moth. It gives us only "fabled wings" and nights that might have "turned incandescent." The word "fabled" makes the visitor sound like a legend the plant has heard of but never met. Because the creature stays unnamed, its absence becomes the poem's real subject, and the reader ends up knowing more than the speaker does.
The imagery shifts with this loss. The flowering "panicle" becomes "a pale flag / that no one ever salutes." The first stanza's vocabulary of blades and keen edges was already faintly military, so the flag completes the picture of a lone sentry at a post nobody inspects. The bloom, which should be the plant's most inviting feature, is reduced to a signal sent to no one.
The form is plain and quiet. There are three six-line stanzas of free verse, with short lines that break mid-phrase and no fixed metre. The one full rhyme, "keep" and "deep," belongs to the confident opening. Once doubt enters, rhyme never returns, so the poem's sound loosens as its certainty does. Small details of layout also work on the reader. The ampersand in "months / & months" looks like a mark of economy, appropriate for a plant that wastes nothing. The word "sand- / stone" is split across a line, so "stone" begins the next line with some weight before "run deep" closes the thought.
The final stanza is the most delicate. "This couldn't be exile, could it?" is a tag question, the kind we ask when we want to be reassured and suspect we won't be. "Exile" suggests the yucca wonders whether it has been put somewhere it doesn't belong, though the poem never says whether that is true. Then comes the odd comfort of "There's desert enough here / for those who wait." This could be consolation, since the landscape suits patience, or it could be a sentence, since the landscape is made for waiting. The poem leaves both readings open.
It ends on an image rather than an answer. Through the dry season, the "flower stalk's bony shadow / creeps over the smooth white drifts." The sounds are soft and hushed, with the s, sh and sm of "season," "shadow," "smooth." "Drifts" makes sand sound like snow, a gentler word for an emptiness. The stalk, once the site of the plant's hoped-for fulfilment, is now "bony," and its main effect on the world is a shadow that moves slowly across the ground like the hand of a sundial. The flowering has produced nothing except a record of time passing.
What makes the poem worth reading is its restraint. The yucca never complains or begs. It speaks in dry, factual sentences and lets a few chosen words, "fabled," "salutes," "exile," carry the ache. Giving a voice to a plant lets Bonta write about longing without the sentimentality a human speaker might invite. We can read the poem as botany, as a portrait of any well-defended creature that still wants to be reached, or as a meditation on being fitted to a place yet unfulfilled in it. The poem holds all of these readings without choosing between them.
