In that photo by Vina Michaelides they're Oxalis purpurea, Joanna (I have to downgrade the facebook photos so that the smaller files download reasonably quickly for people using cellphones etc); you'd have probably spotted that they were Oxalis if you'd seen the higher-resolution original. It's actually very rare to see such a deep pink in Cyclamen hederifolium, though you can occasionally find them. We've got one such plant here in the UK so this morning I was very pleased to see a bumblebee busily fertilising it then, with legs covered in golden pollen, going on to its neighbours to fertilise them!
I'm sure your plants will eventually build up into sizeable patches as the ants gradually spread the seeds around.
