Gorham Can Claim Maine’s First Tomato by Robert Lowell

Gorham [Maine] claims it was the first town in Maine to grow a pomme d’amour, which translates into English love apple.
They are no longer called love apples. They are called tomatoes.
In 1820, the Rev. Timothy Hilliard, who married the niece of Colonel William and Madam Elizabeth Tyng, raised a clatter among the curious with the strange new fruit.
According to “McLellan’s History of Gorham,” when a basketful was brought to Gorham’s village to sell, most rotted and were cast away. Only a few were sold for a penny each. No one knew whether they were to be cooked or eaten raw.
A native of South America, the strange fruit went unloved, at first, in Gorham.
The Hilliards received the seeds from a Professor Peck, of the Botany Department at Harvard, who touted them as a health food. They were grown in the university’s botanical gardens in Cambridge [MA].
But they were widely thought to be poisonous, and once were known as a “wolf peach,” according to the Encyclopedia Britannica.
Introduced to Europe in the 1500s, it supposedly was grown first in the United States by Thomas Jefferson in 1781. They are still being grown in Gorham 160 years later. They belong to the plant family lycopersicon esculentum.
Colonel Tyng’s mansion was known in recent times as the DeWitt Manor. The farm where the tomatoes were grown is now adjacent to the realty office at 652 Main Street.
Colonel Tyng was the sheriff of Cumberland County before the American Revolution and received a commission in 1774 as colonel before fleeing Portland as a royalist.
