In previous posts, I’ve written about flower language in Darling in the Franxx, including floral reproduction, basic genetics, and the names of the plantations themselves. The series’ use of floriography has been a straightforward roadmap — Darling in the Franxx eschews subtleties for directness both visually and in its use of symbolism or literature.
There are a few flowers that have gone unmentioned that are far more relevant now — the hibiscus flower and the cactus — in addition to revisiting Kokoro’s Franxx robot: Genista. Hibiscus and various cacti appear multiple times in the Mistilteinn garden alongside the Franxx robots’ various namesakes. These flowers make up the backdrop of Kokoro’s conversations with Mitsuru, which later leads to their partner reassignments and, in the most recent episode, a sexual partnership.
