Yellow Bells (Tecoma stans)
Mexican Sunflowers (Tithonia diversifolia)
May is clearly the best month for yellow alien invasive species in the Kingdom of the Zulu. This year seems to be showing a massive leap in populations.
Mexican sunflowers are scraggly shrub growing up to 3.5 M high. Yellow bells is an evergreen shrub or small tree. Very ornamental
