This Gazania's outer petals reflect strongly UV around 365nm, and there are also highly UV reflecting marks inside around a dark UV center, all invisible to us humans, but all this gets nicely visible, also in simulated bee and butterfly vision.
I have written about Gazania previously HERE
Stay tuned, more will follow on that fascinating subject...
