alpine collection
Denver Botanic Garden’s Alpine Collection is most likely the largest in the country with regards to number of species. The plants in this collection are described as either truly alpine plants or plants that grow in pseudo-alpine habitats such as rock crevices (Chasmophytes) or exposed locations (Facultative Alpines).
The Alpine collection is especially rich in the numbers of species it contains in certain genera.
