Symmetrical Asymmetry – Cactus, Pastel on Board, 16×20″, 2017, by Jean Krueger, copyrighted with all rights reserved.
This plant grows in a traffic median close to where I stay. I’ve been watching it over the years and it’s grown large and gnarly. I don’t know the name of the species but continue to search for it.
Cacti are generally quite symmetrical in their growth patterns. This example tries to defy that truism with it’s asymmetrical branching. However, the undulating surface of the branches, while not symmetrical, follows in a pattern which repeats somewhat symmetrically. I find that feature fascinating.
