Hines Nursery is a very large plant supplier for many locations throughout California and Oregon and after Color Spot purchased Hines they expanded their distribution to many more locations. In 2018 TreeTown USA purchased the Hines Division of Color Spot and between California and Oregon they have over 2,000 acres to house their nurseries. The Hines Nursery used to be located between Vacaville and Fairfield but they quickly outgrew that location so they purchased land between Vacaville and Winters in the Allendale area and expanded significantly. The nursery does not sell plants directly to the public because they are a wholesale distribution center. The nursery is clearly visible from Interstate 505 and I have seen (mostly before I retired) people stopping beside the freeway taking pictures. I guess they like plants.
Points of interest
The Nursery expanded so much that they had to purchase a second parcel of land located not too far from the original nursery.
