Eric Evans, Let's Talk Garden Speaker for March 2022

3/10 – A Brief Context of Contemporary High Art Horticulture  

Speaker: Eric Evans, Horticulturist, Chanticleer Intern 

Ever wondered how much expertise and artistry goes into the Smithsonian landscapes?  Eric takes us on a tour of different gardens throughout history to explain how horticulture came to be how it is, what it aims at, and what it can be for.  If you’re new to gardening, or if you’re interested in a big picture look at gardening’s end goals, you’ll appreciate Eric shedding some light on the context of modern high art horticulture and how the Smithsonian Gardens fits in. 

Regarding slides with multiple photographs, plant ID’s read from left to right when in a row or clockwise

Several of the aquascapes are by James Findley, including “Through a Child’s Eyes” featuring
Aponogeton crispus ‘Red’ and “Arizona,” A point I was unable to make due to time is that flowers bred for use by florists are often bred for subtler and more interesting color than plants bred for use in gardens, where showiness is considered saleable. I hope to see high horticulture in the future make use of plants bred for the cut flower industry and work with color in a more nuanced way.
