It is possible that the different flower colours are linked with liking for slightly different conditions for germination, and you managed to pick the conditions that favoured the purples.

Thank you Kay. You might be on the right track actually. A couple of weeks after I transplanted the seedlings a large number of them died very suddenly while the remaining ones thrived. There was nothing in between.
Do you think the dead ones were the other colours? If so does anyone have any ideas what I could do next year to help the other colours survive.
I understand that wild Matthiola Incana is purple. Could this be the reason why the purple ones are hardier?
