I love Rainbow Shower Trees. Their flowers come in yellow, as in this photo, red, a sort of hyrid of these two colours, white with a hint of yellow, white with a hint of red. For me a Rainbow Shower Tree in full bloom sings to me of joy and happiness, and on a hot day a mature tree offers plenty of shade.
This is not the best photo of Rainbow Shower Trees, but when I rounded the corner and saw them on this hot day, their brightness called out to me.
