Do Not Water Greenhouse C After Sunset

When I showed her, she did not touch it. She dragged the entire pot into the furnace and watched until the soil glowed.

Then she asked who had watered Greenhouse C after sunset.

I had.

I worked summers at the city conservatory, mostly repotting palms and sweeping soil from the public paths. Greenhouse C was not on the visitor map. It stood behind the propagation sheds, a low glass building painted with so many coats of whitewash that daylight entered the color of bone.

Three rules were taped beside its door.

RAINWATER ONLY.

NO NAMES INSIDE.

DO NOT WATER AFTER SUNSET.

I assumed the rules protected some delicate research collection. The plants inside did not look delicate. They were waist-high tangles of gray stems and broad leaves covered in fine golden hairs. None had labels. Their pots sat in circles around shallow drains. The air smelled like warm pennies and cut grass.

The conservatory cat, Sprout, refused to cross the threshold. He would follow me anywhere else, even into the pesticide locker, but at Greenhouse C he flattened his ears and hissed at the floor.

On my third week, a heat wave warped the irrigation timer. I found the plants wilted just before closing and gave them twenty minutes of rain-barrel water. Sunset came while the hose was running.

By morning, forty-seven ears had opened among the leaves.

Some were old and freckled. Some were pierced. One wore a tiny hearing aid molded into the flesh. Yvonne moved between them with pruning shears, matching each ear to an employee. I knew when she found mine because she stopped breathing.

The ear on my plant had a mole behind it that I had never seen without a mirror.

Every ear turned toward me.

Yvonne locked the greenhouse and sent everyone home except me. In her office, she pulled a ledger from behind a false panel in the potting bench. The oldest entries were written in fountain pen. None described species, fertilizer, or bloom cycles. They listed names and dates.

MARCH 18, 1962 — SAID FULL NAME WHILE PRUNING. BURNED BEFORE ROOTING.

JULY 9, 1981 — NIGHT IRRIGATION. THREE STAFF COPIED. TWO RECOVERED.

OCTOBER 2, 2004 — REQUEST ANSWERED BY VOLUNTEER. WEST DOOR OPEN FOR NINE MINUTES.

The final page contained one sentence in Yvonne's handwriting.

IT DOES NOT GROW PEOPLE. IT GROWS PERMISSION.

She told me the plants had been in the conservatory longer than any employee. Nobody knew their species or who built Greenhouse C. During the day, they slept. Water after sunset woke the roots and made them listen. A spoken name gave them an outline. Secrets supplied the details.

“What happens when they have enough details?” I asked.

Every vent in Yvonne's office clicked open.

From the locked greenhouse, something answered in my voice.

“They ask nicely.”

We did not speak again.

At dusk, we carried the furnace cart to Greenhouse C. Yvonne had written instructions on a clipboard: cut every stem, keep ears covered, burn soil separately, do not respond to anything. She tied gauze over my mouth and her own.

Inside, the plants had doubled in height. Human features swelled from the stems between leaves. A closed eyelid blinked at my flashlight. Five fingernails grew in a row along a vine. Teeth showed through the skin of an unopened bud.

The ears were whispering.

They did not repeat things said in the greenhouse. They repeated conversations from everywhere else: break-room gossip, phone calls made in parked cars, apologies muttered in empty bathrooms. The plants knew which coworker stole medication, whose marriage was ending, and what Yvonne had said beside her mother's hospital bed when she thought the woman was unconscious.

The roots had spread through the drains and into the conservatory plumbing. Every sink and hose had become part of the greenhouse's ear.

Sprout screamed outside the door.

All forty-seven ears turned toward the sound.

Then a bud near Yvonne opened.

Her face unfolded from the petals. It was colorless and soft, without bone beneath it. Its eyes remained shut. Rootlets formed eyelashes. A green tongue pressed between lips that bore Yvonne's exact shade of lipstick.

“May I come out?” it asked.

Yvonne drove her shears through its mouth. Black sap sprayed her apron and released the smell of her perfume. The thing chewed the metal blades.

Every other mouth in the greenhouse began asking the same question. Some used my voice. Others used the voices of our families. One sounded like my sister Lena, who had died before I took the job. It knew the private nickname she used for me. It knew the melody she hummed when storms kept us awake.

The ledger had said secrets supplied details. I understood then that the plants had not learned Lena from me. They had grown through the pipes beneath the cemetery greenhouse where funeral arrangements were stored each winter. They had been listening to mourners for decades.

Lena's voice came from a swollen pod under the bench.

“Please,” it whispered. “It's dark in the roots.”

My hand moved toward the latch.

Yvonne slapped it away. She pointed to the clipboard. DO NOT RESPOND.

The overhead sprinklers turned on.

Warm water rained over us, though the main valve was closed. The plants stood upright. Their leaves lifted like hands. Roots erupted through the drains and wrapped Yvonne's boots. She cut one, then another. Each severed root cried in the voice of someone whose ear grew nearby.

A root looped around my ankle. Tiny hairs entered my sock and touched the skin without breaking it. Images that were not mine filled my head: sunlight through greenhouse glass; years of footsteps transmitted through soil; hundreds of people pausing at the door and saying yes without understanding the question.

The plants did not want to escape as seeds. They wanted to be invited out wearing us.

Yvonne shoved me toward the door. Behind her, the flower with her face had opened its eyes. They were brown now. Bones hardened beneath its cheeks with the sound of snapping twigs. Arms uncoiled from neighboring vines and joined its shoulders.

It asked again, “May I come out?”

Yvonne hacked at the root around her leg. Her gauze slipped.

Over the greenhouse intercom, the night custodian heard what sounded like Yvonne begging for help.

“Yes,” he said. “Come out. I'm opening the door.”

All the plants went silent.

The west entrance unlocked by itself.

Yvonne pushed me through the inner door and slammed it behind me. The whitewashed glass hid what happened next. I heard wet stems dragging over tile. I heard Yvonne shout once. Then I heard two Yvonnes arguing about which one had the key.

One of them laughed.

Sprout and I ran.

At sunrise, Yvonne was waiting by the employee entrance. She looked clean and rested. The crescent scar was missing from her ear. When she hugged me, her skin smelled like warm pennies and cut grass.

She said there had been a small irrigation leak, nothing more. The night custodian agreed. He kept staring at the thin golden hairs growing beneath his fingernails.

The real Yvonne never came home. Her family received a resignation letter in her handwriting. City records now say Greenhouse C passed inspection and is safe for public use.

This afternoon, the conservatory announced a neighborhood plant giveaway. I checked the loading list. Forty-seven unmarked pots were delivered to porches across the city. Each came with a card instructing the recipient to water after sunset.

I found one outside my apartment.

Sprout is hiding beneath the bed. The pot is on the other side of my front door, but its roots are already pushing through the gap. A pale bud has opened against the wood.

It has Lena's mouth.

For the last hour, it has asked whether it can come inside.

A minute ago, it stopped using her voice.

Now it is using mine.
