These are hands-on internships providing students the opportunity to work alongside our professional horticulture staff and volunteers in the daily operation of maintaining botanic gardens. Work assignments may include such tasks as planting, pruning, weeding, mulching and watering garden areas.

During the summer each intern is expected to complete a project that will expand their horticultural knowledge while benefitting the Gardens. During the summer of 2020 projects will focus on:

Bonsai Collection Management and Curation

Learn and master the skills required to develop and maintain bonsai in a public garden. Assist and study with Denver Botanic Gardens’ bonsai specialist through daily care and longtime development of the bonsai collection. Photography of the collection for inclusion in Denver Botanic Gardens’ living collections database will be a major component of this internship.

Plant Records Curation and Mapping

The plant records intern will work with the plant records team to assist in the curation of the diverse living collections at Denver Botanic Gardens through data basing, mapping, labeling and digital photography. The 2020 intern will focus on documenting the gardens surrounding our new Freyer – Newman Center for Science, Art and Education. This state-of-the-art facility, slated to open in spring 2020, marks the completion of Denver Botanic Gardens’ 2008 Master Development Plan. Future visitors will be welcomed by new gardens designed around several themes: medicinal, rain, literary and woodland.

Urban Agriculture and Rooftop Growing

Assist with the first-year management and promotion of the rooftop vegetable project at Denver Botanic Gardens, building on the Gardens’ existing urban agriculture models. The urban agriculture intern will assist with weekly harvests and data collection in the Home Harvest and Le Potager production gardens. This internship will also provide opportunities to learn from our offsite vegetable production-focused urban agriculture projects.

Therapeutic Horticulture

Gain professional experience working with Denver Botanic Gardens therapeutic horticulture team, leading and supporting program activities and assisting in the daily maintenance of the Sensory Garden. The horticultural therapy intern will create and facilitate participant activities that both fulfill the needs of the Gardens’ horticultural therapy program and their personal interests.

The internships are rounded out with educational field trips, lectures and workshops with other interns. Upon completion of the internship, each intern is expected to give a presentation about their project and experiences.
