They may be...but don't eat them till you're sure ;)

Some look like Allium.

I have a similar problem only with about 20x the bulbs. A friend moved away and I needed to take them before they plowed everything under. I have no identification of them but some are blue color and have the shape of tulip bulbs. The rest are white and all sorts of shapes.

I have them divided visually as best as I could and will be planting them in a test bed. In the spring, I will begin to sort them by what comes up. As with when moving Irises, I will color code the stalks with yarn and take notes to be able to identify them when I move them.

Unfortunately, it may take two years to identify some as they may not all bloom next year.
