that is likely just the older foliage. I don't that it means they wont bloom, only time will tell! hope this helped

Yeah, I guess we'll see. The foliage at least is a good sign that the bulbs are alive I guess.

Something could have eaten the foliage as well, but I'm not sure.

I have had the foilage come up in the fall, stay all winter (not looking the greatest) and then bloom in the spring. It must be certain varieties because all of mine don't do this.

common grape hyacinths Muscari armeniacum have long floppy leaves that grow in fall and persist during the winter. In my garden they tend to smother more desirable plants so I've been trying to thin them out for years despite the lovely blue color.

yeah, they are flopping all over my lily sprouts and daffs..I think they will be ok though.

Muscari do that, with the long leaves in the fall. Mine have been eaten by deer or something. But the plants will send up flowers & new leaves in spring. And the deer will have something else to eat by then.

I planted my muscari bulbs about a month ago, and I was surprised to see the foliage already. I didn't think I would see that until spring.

I'm in Atlanta. Will the plants survive a cold winter here, and bloom in spring?

I hope they survive, mine are up and I will surely have a colder winter than you!
It's entirely normal.

They are very tough little buggers. About as tough as one could ask for. I wouldn't worry. I planted only six last year that weren't that big, had mold on them, and were sent to me as a "free gift" with a purchase. I washed the mold off and planted them. They grew big and strong. I decided to dig them up to store them once the foliage died. I found the 6 had turned into.... dun dun dun: 86. So they are very prolific too.
You should be fine.

I would actually really advise NOT cutting the foliage off. As long as they have spent the energy of growing foliage, let them harvest and store as much sunlight as possible before they go into dormancy again.
