Could be crocus, grape hyacinths or other spring blooming flower bulbs? Whatever they are, they need to be separated & replanted.
don't seperate unless they are dormant after they have died back naturally after growing has stopped.
I believe they are daffodil bulbs, so many cluster of bulbs .
Now that I can see the bulbs better in 2nd pic, the bulbs could be early summer blooming lilies such as Asiatic or Oriental lilies. Notice the way the bulb seperates into clove-like sections. That is probably some kind of a lily!!
Elizabeth from NC - PLEASE DO NOT SEPERATE THESE BULBS!! These bulbs are suppose to look this way. Just replant them!
I agree with Carol, they look like Oriental Lily bulbs! How pretty!
they don't "need" separated & surely not unless they are dormant. There are hundreds of bulbs you need to let them bloom to see then mark them.
