Tecoma stans is a Mexican and north eastern Africa evergreen annual shrub, 2-4m tall with dense leaves and yellow flowers. Yellow bells produce masses of wind-dispersed seeds and readily invade the margins of native bushland as well as along roadsides. It falls under the category one plants of the Conservation of Agricultural Resources Act (CARA). Plants from this category are prohibited on any land or water surface in South Africa and must be controlled or eradicated where possible.
The invasion by yellow bells plant displaces indigenous plants and animals; reduces the productive potential of the land and impacts on biodiversity. It was brought to South Africa for ornamental purposes. Yellow bells plant has been recorded inside and outside Kruger National Park as well as in other areas in the lowveld.
The control of yellow bells oil plant is limited to herbicide control only. Should you have yellow bells plant in your area, contact the Invasive Species Control Unit/ Working for Water KNP for further investigation and clearing assistance.
