Congratulations! I hope your kids were thrilled!
I have to admit after contributing to this thread, I ran to the fruit basket and found an apple that was late summer/early Sept maturing variety, so I tried sowing the seeds. I think I put some in a flowerpot outside, and I put some in some of the indoor pots. I actually didn't even record the name of the original apple, and all I can say is that it sprouted some time ago, but I have a seedling growing next to an avocado seedling right now.

Initially, I didn't even know WHAT it was.

I'd been burying seeds from every fruit I ate like a squirrel for a while.
Edited to add on March 25:
Here's a photo. It's been doing well in this SE window. I just up-potted it into a 4x4x5D pot.
