May I ask the age of your camellias? I have 2 at home, they are minuscule compared to yours!! LOL
And they need a bigger pot.
Flower size is big though, for a small plant.
Glad that this Cattleya orchid is finally flourishing. Once a few years.
2 other flourishing orchids:
Very tiny flowers - 1 cm (0.4 in)
Phalaenopsis - 3 bloom spikes
