NEW YORK — Jessica Tcherepnine, a British-born watercolorist whose meticulous, naturalistic depictions of flowers, fruits, and vegetables established her as one of the world’s leading creators of botanical art, died Dec. 31 at her home in Manhattan. She was 80.
Her husband, Peter Tcherepnine, said the cause was complications of corticobasal degeneration, a progressive neurological disease which led her to stop painting four years ago.
Her portraits — of pumpkins and peppers, mushrooms and morels, coconuts and quinces, and more — combined a delicate artistic sensibility with superb technique, and scientific accuracy with a passion for nearly anything that grows out of the ground.
Her joy in exploring her subjects was evident in a question she posed in an article for the American Society of Botanical Artists in 2014.
“What could be more wonderfully weird, or more weirdly wonderful, than the seed pod of the Strelitzia nicolai?” Ms. Tcherepnine wrote about the tropical plant better known as the white bird of paradise, which has banana-like leaves and clumping stalks. “I have painted these seed pods several times. Each time I see new and exciting details of the shapes and colors.”
She recalled searching in Florida for the group of black seeds that would provide the ideal finishing touch to one of her bird of paradise watercolors.
Ms. Tcherepnine was a star of her corner of the art world. She won two gold medals from the Royal Horticultural Society, the British gardening charity. She was also invited to paint the beet (beta vulgaris) for “The Highgrove Florilegium,” a 2008 book that records all the plants in Prince Charles’ garden in Gloucestershire, England.
Her paintings are in the collections of the state Peterhof Museum in St. Petersburg, Russia, and the National History Museum in London, among other places. Some of her artwork is also in the expansive private collection of Shirley Sherwood, a British botanist, writer, and philanthropist.
“She produced strong, individual plant portraits which were arresting,” Sherwood said in an e-mail. “She also chose interesting subjects at a time when there were far fewer botanical artists than today and there was a tendency to paint only pretty, popular subjects like roses.”
Beginning in 1983, Ms. Tcherepnine was the subject of several successful exhibitions at the Shepherd Gallery in Manhattan, which stepped out of its specialty in 19th century art to showcase her paintings.
“The reason we show her work — she’s the only botanical artist we do show — is that it is not old-fashioned,” Robert Kashey, the gallery’s director, said in an interview with The New York Times in 1997. “The lines, the clarity, the magic she creates, the emotion she has for the plants. That’s why she’s one of the best.”
Ms. Tcherepnine was also a longtime board member of the Horticultural Society of New York, for whom she taught botanical drawing to prisoners at Rikers Island.
“She’d come out several times a year and talk to the inmates about the colors and elements of a flower,” Sara Hobel, the society’s executive director, said in a telephone interview. “Once, she conducted a fantastic discussion with them about pepper plants.”
Jessica Elizabeth Harris was born May 14, 1938, in Sussex, England, and grew up there and in London. Her father, William Barclay Harris, was a lawyer, and her mother, Elizabeth (Milnes Coates) Harris, was a homemaker.
As a child, Jessica drew and painted flowers — blossoms in particular — in her family’s garden. After attending a girls boarding school in England, she studied drawing and watercolors for several months in Florence, Italy, with the noted teacher Nerina Simi.
She found work in the art world in the 1960s, mostly as an assistant in various departments of Christie’s, the auction house, in London and in its Manhattan office. She married Peter Tcherepnine, an investment manager, in 1973 while living in the United States.
In 1982, she left her job to focus full time on botanical painting.
“When I am doing a painting, my subject is the last thing I look at before I go to bed and the first thing I look at when I get up in the morning,” Ms. Tcherepnine wrote in the article for the American Society of Botanical Artists. “And I am thinking about it in between.”
In addition to her husband, she leaves a sister, Hermione Karlin; a brother, Jonathan Harris; a stepdaughter, Samantha Tcherepnine; and three step-grandchildren.
Last year, Tcherepnine donated the use of her portraits of a garden beet, quince, apple, hydrangea, banana, and woods’ rose for note cards by CurePSP, an advocacy organization that seeks to combat prime of life neurodegenerative diseases like corticobasal degeneration and progressive supranuclear palsy.
“Even as her physical capabilities diminished, her intellect remained crystalline and her sly English sense of humor intact,” David Kemp, president of CurePSP, wrote in an e-mail, recalling her visits with her. “She was the Audubon of plant life.”
