2016 Tree Diversity Conference - DESIGN WITH MORE. TREE. TYPES.

For a third consecutive year four noted speakers will share more ideas for diversifying the Colorado Front Range tree species palette and how to make them feel welcome and prosper in our difficult high plains conditions.

Our focus this year will also be on the way tree species diversity can enable and enhance innovative landscape design whether for water conservation or esthetic objectives.


Increased species diversity is not just about tree census numbers but also about improving our approach to landscape design. Our third tree diversity conference will focus on how greater tree variety can enhance landscape esthetics and conversely, how innovative landscape design can accommodate a broader range of tree species.

The March 3, 2016 program will feature one of the foremost horticulture professors from the Front Range; a noted landscape architect with extensive xeriscaping experience in Texas and New Mexico; a Washington state horticulture professor noted for science-based debunking of arboriculture myths; and a Midwest arboretum owner, author and introducer of new tree cultivars. In addition we will hear a presentation on how many of the lesser-known tree species already growing in our region fared when tested against the severe weather events of the past year.

A Midcentury Icon: 50 Years of the Boettcher Tropical Conservatory

The Gardens’ Boettcher Memorial Tropical Conservatory was completed in 1966. The building has been a midcentury architectural landmark for 50 years. Designed by architects Victor Hornbein and Ed White, the 11,500 square foot building took two years to build and is the only conservatory in the country made of cast-in-place concrete. Even before its completion, the building won international recognition for its unique design and unusual structure. More than 600 species and varieties of tropical plants are displayed. The tropical terrain includes pools, waterfalls and four resident ducks.


To celebrate this anniversary, the Gardens is hosting a special event. Guests are invited to enjoy 60s-themed appetizers and nonalcoholic beverages, tours of the conservatory and a presentation in Mitchell Hall featuring a video interview with lead architect Ed White, Dan Havekost associate architect and Richard Breaker from GH Phipps Construction. A panel discussion with architecture and history experts further explores how this building has been an icon on Denver’s architectural landscape and continues to inspire architects and enthusiasts of midcentury design. The conservatory will open to allow the rare opportunity to tour the space with horticulturists and docents after dark. Markers will identify plants that have been present since 1966.
