The strangest Jacaranda tree ever!

I noticed this tree last year at this time. At this time of the year, the Jacaranda trees in Joburg (where I live) produce really beautiful purple flowers. The whole of Joburg looks like it is covered in a purple cloth, it’s really pretty. I have never seen a Jacaranda tree produce a flower of any other color, except this one odd one in the park near my house. Different color flowers on a Jacaranda tree would be odd on it’s own, but this Jacaranda tree goes beyond that. This tree has 2 x branches that produce white flowers, while the main stem/branch produces the normal, purple colored Jacaranda flowers. That’s right, 1 tree, 2 different color flowers, depending on the branch they are on! Strange to say the least!
