Wow, you show here 4 lovely flowers, one prettier than the other.....and my favourite one is #3, because of her balanced shape, her dot patterns are not melt to a single dark area and the green markings on the staminode.
I love them all, each for their characteristics!
What are the size of the individual flowers? (Just a simple measurement, f.ex. across, would be fine... it's just to get an Idea!)
