PITTSTON — The Pittston Consolidated School has a new greenhouse, dedicated to the memory of Allison Keaveney, a fourth-grader at the school who died 30 years ago.

After Keaveney was struck and killed in December 1982 when she tried to cross a road while wearing ice skates, her family began a tradition of having students sell plants at the school to raise money to support arts and humanities projects.

After 30 years, the Allison Keaveney Fund is going strong.

“It’s awesome. The kids are so thrilled with this,” Principal Shelley Simpson said of the new greenhouse that was dedicated on May 11. “It is very important that we keep the spirit of Allison Keaveney alive. It’s important to the school and it’s important to the community.”

A stone dedicating the greenhouse to Keaveney’s memory was placed in front in a ceremony attended by Keaveney’s mother, Mary Szaro, who now lives in Massachusetts, and other family members.

The first plant sale netted a profit of just $80. But the sale grew and grew, until this year the sale the weekend of May 19 netted a total of $4,400, with a profit of $3,300. The greenhouse, a $1,700 Home Depot kit, was paid for out of the Keaveney Fund and assembled by parent volunteers on April 23.

“It’s beautiful,” said Simpson. “With the greenhouse, the plants just grew and grew.”

Simpson said money from the Keaveney Fund has been used to take Pittston students to performances at the Maine State Music Theater in Brunswick and to pay to have an artist-in-residence and an author-in-residence at the school. The fund also has brought theater troupes to perform at the school.

Before the greenhouse, students started their plants in small pots on classroom windowsills as early as February. They also have two growing labs inside the school.

The greenhouse, which runs on solar heat, is 10 feet by 12 feet and made out of hard, clear plastic. It has a window that opens and closes on its own to keep the temperature inside the greenhouse at a steady level.

“Our goal is to use it from early fall to late fall and from early spring to early fall,” Simpson said. “Eventually, we hope we can use it all winter.”

Simpson said having plants growing inside the greenhouse will enhance science classes at all levels of the school, which has 182 students in kindergarten through grade five. “They can use it for different aspects of science such as habitats and life cycles,” she said.

Jen Hebert, mother of second-grader Maddie, said she went to school with Allison Keaveney. Hebert said many of the parents of today’s Pittston students were students themselves when the nine-year-old died.

“Hundreds of people bought plants this year,” said Hebert, who helped organized the plant sale. “The kids had tomatoes, morning glories, petunias, marigolds, pansies and many different kinds of flowers and plants, including perennials.”

Prices on the plants ranged from $2 for small plants to $30 for large bushes.

She said Gingerbread Farm in Wayne supplied many of the perennials for the sale and local businesses also contributed plants.

“The whole gymnasium floor is covered with flowers on sale days and the perennials are outside,” said Hebert. She said having all the flowers and plants at the school at one time makes for a colorful scene.

She said a few of the perennials are left over and people take them home and plant them for use in next year’s sale. Students also are given a chance to buy leftover plants after the sale.

“Volunteers have kept it going,” Hebert said. “It’s been really good.”
