If you've just got apricot ones and the neighbours haven't got purple ones they're more likely to seed true.
I don't grow apricot ones but I know what Hostafan means from other seedlings. Seed leaves often show colouring that disappears later on.
eg Mirabilis jalapa. I can tell the bright pink from the pale ones immediately they germinate but after the true leaves start they all look the same.
