Nope, not usual, it's a fluke...
But what a pretty fluke it is...

What happens as far as I understand it is,
that 2 seeds are together when sprouting,
and they are sooooooo close together~that
they merge together...hence growing together..

I had that happen with a dandelion...
It had 3 flowers growing together..

I've also seen trees that do this in the woods.

But Thanks for sharing that with us..
I't always so neat to see pictures..

Don't forget to be kind to strangers. For some who have
done this have entertained angels without realizing it.
