I received this in a trade here on the forum back in Sept. 2019. The plant itself, has done pretty well and is now in need of dividing. I planted another plant in the same trade right next to it 'Morning Comes Electric' which has performed much better as far as increase, and it is a much larger plant and larger clump.
The problem with both plants was that the blooms were never distinct and vivid in their colors and pattern and for two years I had a lot of trouble telling the bloom on one plant from the bloom on the other. It just seems to me both plants might be more suited for a northern climate to really bring out their best bloom colors. Since I now spray for rust and I have no early notes about rust for this plant I can't really comment on the rust factor.
It has not been a favorite of mine and I can't recommend it for this area. I only show to have two bloom photos over the years and neither one of them is very good.

I found scapes deep inside the clump:
