Located in Central Colorado, Bishop Castle has quickly become one of the most popular roadside attractions in the state. In 1959, fifteen-year-old Jim Bishop dropped out of school and purchased a 2.5 acre piece of land for $450. This piece of land was located alongside southern Colorado’s San Isabel National Forest. In order to earn enough money to purchase the land, Bishop worked random side jobs and helped his father, Willard. Although Bishop funded the land purchase, his parent’s legally owned the land since Bishop was only a teenager.
The Annual Flower Trial Garden is a devoted horticultural research garden on the campus of Fort Collins' Colorado State University, open to the public throughout the year near the campus' Center for the Arts. The garden strives to serve as a trial space for the performance of annual plant cultivars in the region's high-altitude Rocky Mountain environmental conditions, with primary annual plantings on display between late May and mid-October. Plant varieties are grouped by genus and arranged by color, with more than 1,000 different cultivars typically on display each year. In addition to the main annual showcase, the garden also presented an annual pansy display, which is planted in fall and on display through the early spring. Perennials cultivated by the garden are also on display year-round across the street from the garden facility.
