A nice change-up cute feature is that one of the flowers can be seen to have rabbit ears. That particular flower didn't develop an upper sepal. No dorsal sepal. Nice probabilistic outcome.

Above: rabbit ears, doing 'star jumps' or 'snow angels'. The overlap of the two petals creates that dark-coloured over-lap region that can be seen (in the over-lap region).

Above: the flower on the left-hand side is the one without the upper sepal.

Above: upper flower is the same flower - no dorsal sepal.
