Q.Will my mums come up through begonias that I accidentally planted on top of them
I like begonias as beautiful annual ground cover …. I can never remember where I planted my mums (they are strong, healthy and come up every year). Do I have to pull up the begonias or will they strong healthy mums come up through them ?

Typically, you will see the new growth of mums in early spring. If you didn't accidentally pull up the mum roots when you planted the begonias, I would think the mums would come up around them.
Some mum varieties only come back a few years, others not at all. So don't be dismayed if yours didn't return this year.
Here is more information about the lifespan of mums:
