Nut Tree is a mixed-use development in Vacaville, California near the intersection of Interstate 80 and Interstate 505. It opened in 1921 on old U.S. Route 40. It was created by Helen and Ed "Bunny" Power as a small roadside fruit stand, and built near the site of Helen's childhood home ('Harbison House' dating from 1907), which she and her husband purchased from her parents not long after their 1920 marriage.
The Nut Tree grew as US 40 became Interstate 80. At its peak, it contained a restaurant, an outdoor eatery, a bakery, a gift shop, a toy shop, the Nut Tree Railroad that gave rides from the toy shop to the airport, and an airport, which is now owned and operated by Solano County. It was a welcome rest stop on the road between Sacramento and the San Francisco Bay Area. Throughout the year, kids enjoyed giant frosted honey cookies (personalized on request), the numerous "Hobby Horses" rocking horses and riding the train.
It welcomed several celebrities, including Ronald Reagan when he became California governor in 1967, Richard Nixon, Danny Kaye, Shirley Temple Black, Peter Marino and Bing Crosby, among others. On March 4, 1983 Nut Tree catered a luncheon hosted by CA Governor George Deukmejian for Queen Elizabeth II and Prince Philip at the State capitol
Beginning in 1980, Nut Tree was home to a month-long October harvest event called 'Pumpkin Patch'. Pumpkin Patch attractions included a great scarecrow contest, a giant pumpkin display and weigh-in, and pumpkin carving contests.
The Nut Tree Restaurant was an early pioneer of California cuisine, with fresh fruits and vegetables featured in the recipes. By 1978, it was identified as "the region's most characteristic and influential restaurant." It also featured small loaves of wheat and rye bread, cooked fresh each day on the premises. A notable feature of the restaurant was its large indoor aviary, which had glass walls extending from floor to ceiling. Nut Tree knives and cutting boards, as well as books on aviation, were sold in the gift shop. A recipe book called Nut Tree Remembered - The Cookbook was printed by the Vacaville Museum in 1997. It contains 40 recipes, and more than 100 photos and graphics from the restaurant and retail stores that closed in 1996. As of September, 2015, they still accept phone orders for the remaining copies.
