When I went to check the daily new blooms on my hibiscus plants, I discovered this yellow beauty
on this red plant https://pbase.com/britestar/image/169312826

I don't quite understand what is going on. Although ruffled, even the petals seem to be a bit different. Red flowers were also still on the same plant; along with this lone yellow and red one. The red flowers are also larger than the yellow one.

To date, this has been the only yellow bloom to appear. Very odd.
