Meet the 95-year-old Vermont herbarium volunteer who had a fern named for her

BURLINGTON, Vt. (InvestigateTV) — For 28 years, Hilda White has shown up at the University of Vermont’s Pringle Herbarium to do a job most people have never heard of: mounting plants.

Now 95 years old, White has carefully preserved more than 50,000 plant specimens — pressing and affixing them to archival paper so they can be studied and referenced for generations to come.

“If I mount the plants, the plants will be around for hundreds of years, barring any unforeseen accidents or anything,” White said.

Birthday gift unlike any other

For her 95th birthday, the herbarium gave her a gift unlike any other: a newly discovered fern, found in Colombia in 2023, was officially named for her.

The plant — a Christmas fern — was discovered by Wes Testo, now the director of the Pringle Herbarium collection, during a research trip to South America.

“I was walking through the forest there, and I saw this just spectacular fern,” Testo said. “I knew immediately it was something I hadn’t seen before.”

After further research confirmed it was a species new to science, Testo and his colleagues decided to name it for White: Polystichum hildae.

“Oh, I was absolutely blown away,” White said when she learned of the honor.

“You can’t imagine, I cried all afternoon.”

‘Library for plants’

White’s work at the herbarium is kind of a library for plants.

“I can’t draw, but this is my artistic outlet,” she said.

Testo said White’s contributions have been essential to the research conducted in the collection, which now houses 400,000 plant specimens in a single room.

“Hilda mounted a huge amount of the specimens you see here,” Testo said. “Her contributions are absolutely essential to the research we do here.”

The collection’s survival is not something White or Testo take for granted. In 2017, a fire broke out at Torrey Hall, where the collection was housed at the time. Testo was in South America doing research when he received word.

“All I could see from an email in Colombia — the roof on fire. I thought my whole Ph.D. was going up in flames along with the whole collection here,” Testo said.

White was on her way into work when the fire broke out. Staff and volunteers, including White, worked to restore and remount the damaged plants. The collection has since been relocated to the Jeffords Building.

No plans to stop

White says she has no plans to stop.

“Oh no! I’ll be here as long as I can,” she said.

And when asked what she planned to give Testo for his birthday in return for the honor of having a plant named after her, White kept it simple.

“He just got good wishes!”
