I live in Zone 3A and have a mixed rose border with lots of bulbs in it.
I
applied a heavy mulch of leaves over my bulbs a good while after
freeze-up.
This is the third year I do this mulching.

Now I looked under and lots of Muscari are poking up. Oh dear. There
must
have been more heat still trapped in there than I thought.

What's odd is I thought this growth could not happen without a good hard
cold dormancy period. My tulips, narcissi and everything else are not
coming up. I certainly can't save the muscari from the rest of winter.
So
I just put the leaves back.

Don't worry about it. Nothing will kill them and eventually they will take
over your bed. Mine have been up for a couple of moths here in zone 6.
They will be just fine and bloom as expected in the spring.
