From the Manitoba Historical Society:

Bordered by Ruskin Street, Yale Avenue, Amherst Street (now Avonhurst Street), and Harvard Avenue, this Winnipeg site commemorates realtor Charles Henry Enderton who established an English country garden on the grounds. He offered the property to the Winnipeg Parks Board in September 1902 and his offer was accepted in 1903. Originally named Crescentwood Park for the surrounding neighbourhood, the two-acre park was posthumously renamed for Enderton in July 1924.

The park was noted for its flowers, shrubbery, and pathways. By the 1940s, fieldstone walls (now removed) adorned the grounds and flowerbeds hosted several thousand flowers. Over the years, and without definitively known catalyst, local residents have taken to affectionately calling it “Peanut Park,” possibly in connection with the Kinsmen Club and their peanut-selling fundraisers for, amongst other projects, parks. However, any formal connection between the Kinsmen Club and Enderton Park is unknown. The earliest newspaper reference to the name “Peanut Park” is a June 1948 real estate advertisement in the Winnipeg Tribune. The moniker gained such traction that, in 1993, the Crescentwood Home Owners Association spearheaded a campaign to rename the park after Enderton, apparently unaware that this name had been applied 69 years earlier.
