Nothing to worry about!
I have dozens & dozens of these in pots, in basins, in large pots with coconut husk, mounted on broken clay pots on walls and on coconut husks hanging from my palms. These are extremely hardy, low maintenance, and not fussy whether you give it full sun or bright and dappled direct sun. Leaves will range from medium green to a purplish hue as well. Either way it has never failed to bloom for me consistently from the end of autumn back around till the following summer. Maybe if you asked me I could have given you several blooming size plants for free. Mind you this is just one colour of the several around my yard.
