M. - the bicolor left bottom -is an Optimara Dali. Right bottom is probably Optimara Alaska. I grew both of them some time ago. Dali - is an excellent variety, Alaska - very changeable flowers, depending on who knows what the blue leaches to make the whole flower tinted - or bleaches to almost white.
