Wow. Spontaneous Polyploidy! Quite interesting to see in nature.

This has a complex answer, and I won't bore you with the details.

Sometimes what happens is that some stress, or chemicals, will cause a genetic disruption in plant cells. Instead of splitting into separate cells, all genetic material from cell division gets packed into cell. So the plant is now what is known as "Polyploid"

This will not harm the plant, and can likely die off, never to return, at some point. If you get lucky, you will get seeds from those flowers, which some may be polyploid. This means they have the potential to carry on the genetic mutation.
