Downy thorn-apple (Datura innoxia)

In warmer climates, the downy thorn-apple (Datura inoxia) is an invasive species that can establish and spread rapidly. Native to East Africa and naturalized in regions like China, it poses significant risks if introduced to new areas. The plant's aggressive growth allows it to outcompete native flora, disrupting local ecosystems and reducing biodiversity. Additionally, all parts of the downy thorn-apple are highly toxic to both humans and animals, posing health risks. While it is sometimes grown in gardens, caution is needed to prevent it from overtaking other plants. Currently, there are no widespread bans on its sale, transport, or cultivation, but its spread is generally discouraged due to its invasive nature and toxicity.
