Thaumatophyllum adamantinum reproduces sexually through flowers and stamens. Flowers are inflorescent with a 2–5 cm peduncle, 6.4-11.4 cm single leaf surrounding the stamen (called a spathe), and a 5.5 cm-12.5 cm spadix. The spathe is green with a creamy white inner surface. Flowers have 5 staminodes and cylindrical petals. Berries are oblong and generate 2.5mm long oblong seeds containing oily droplets. {{Citation needed|date=January 2023}}
Thaumatophyllum adamantinum can be propagated by taking cuttings. With a sterilized sharp knife, cut off a section with multiple aerial roots and leaves at a sharp angle. The cutting can then be rooted in water, soil, or in sphagnum moss.{{Cite web |date=2021-11-26 |title=how to propagate a split-leaf philodendron: easy guide |url=https://theindoornursery.com/blog/how-to-propagate-a-split-leaf-philodendron/ |access-date=2023-01-25 |language=en-US}}
Toxicology
Like their relative Philodendron, Thaumatophyllum are poisonous to vertebrates, but vary in their toxicity levels. They contain calcium oxalate crystals in raphide bundles, which are poisonous and irritating. The sap may cause skin irritation.{{cite web |title=Thaumatophyllum adamantinum |url=https://garden.org/plants/view/308237/Thaumatophyllum-adamantinum/ |website=Garden.org |publisher=National Gardening Association |access-date=2023-11-16}}
