Program Description

This presentation chronicles a cactus-focused exploratory trip through central and northern Chile, spanning the diverse landscapes of the coastal and interior Atacama Desert and the high elevations of the Andean Mountains. The objective of this journey was to find as many iconic Atacama and Andean cactus species as possible. observing and documenting them in their natural habitats.

About our Speaker

Szymon’s interest in cacti began in middle school after visiting his cousin’s collection. Upon relocating to California in 2015, he discovered an opportunity to combine several longstanding passions — backpacking, hiking, photography, and botany — through desert exploration. His experience in the backcountry proved invaluable for reaching remote and ecologically significant sites, while his photography skills allowed him to carefully document the specific conditions under which various cactus species thrive — essential for understanding how and why these plants succeed in such extreme environments.

Show & tell table: Haworthia on the succulent side, Copiapoa on the cactus table, and curcurbits (that is, members of the Cucumber Family, including Gerrardanthus, Dendrosicyos, Ibervillea, Kedrostis and Marah) for pachyforms, plus anything else that’s looking good or in flower.

Featured grower: TBD.

Snack table:, There will be a shared spread, but we suggest bringing something every couple of months if you partake regularly. As a thought, we are often short on drinks.
