Does anyone know who I can get my bougainvillea flowers to change colors? I have a couple white ones and now I want them to be the dark red color. There are a few branches on the plants that are turning pink. I know it's possible, because I have seen the plants change colors. Sorry, but I am going to cross post this, because I really want to know.
I know how to get them to change brown.
Seriously though, I would expect if they have this ability it is due to an integrated virus or "jumping gene." Love to know myself.
I've never seen a bougainvillaea change colors, but I've only grown the red, which appears to be the more dominant variety. I imagine some of the red genes are poking through on the white on occasion.
However, you might take a cue from Hydrangeas, by adjusting soil pH you can change their color.
Thanks for checking Cricket. The ones that changed their color were a purple and brown one from HD, so who knows maybe they were spray painted. Plus they died soon after.
