Punching a Duisbergia will not destroy it, but will instead drop the plant as an item. Like most other content in the mod, it does not spawn naturally in the world.
The Duisbergia can only be obtained by putting a Plant Fossil in an Analyzer. There is a rare chance that this will yield Fossilized Duisbergia Spores, which you then must place in a Culture Vat. Unless the culture vat fails and spawns a Failure Plant, it will then turn the fossilized spores into normal Duisbergia Spores which can be planted.
