Kollam: While residents in cities and villages are enthralled by the vibrant yellow blooms of the Cat’s Claw, botanists are raising an alarm. Although social media is currently flooded with pictures of this scenic flowering, experts warn that this is an invasive species that poses a severe threat to local ecosystems if allowed to spread.

The Origin and Nature

Native to tropical American countries, the plant is characterized by its shining tubular flowers. It blooms massively every March, though the spectacle lasts only a few days. However, behind this beauty lies a survivalist nature, the plant employs several aggressive strategies to spread rapidly and eradicate native flora.

Why "Cat's Claw"?

The plant earned its name from its unique climbing habit, using hook-like tendrils to cling to surfaces like a cat’s claws. Dr. K.B. Ramesh Kumar, Senior Scientist at the Tropical Botanical Garden and Research Institute, Palode, explains that while it was once a popular garden ornamental worldwide, it is now globally recognized as a notorious weed.

Due to its destructive nature, several countries have already banned the plant. Its survival and reproduction mechanisms are highly efficient. The reproduction occurs through seeds, tubers, or stems. Its winged seeds are easily distributed by air and water currents. If it cannot find a structure to climb, it spreads across the ground like a carpet, stifling the germination of other seeds. The plant develops underground tubers that act as food storage units, allowing it to survive and regrow over long periods. Also it can withstand adverse conditions, including salinity, frost, and fire.

Control Measures

Dr. Ramesh Kumar noted that many countries are now forced to use biological control methods such as introducing specific leaf-eating and seed-eating beetles alongside chemical pesticides to attempt to eradicate this stubborn invader.
