Where did these bulbs come from?

I found them in the basement, staying cool, and not looking too bad for a living thing. These bulbs, tulips and daffodils, should have been planted outside in October. If you are in this same boat, find some pots, put in about a inch of potting soil, set the bulbs in tight, cover with more potting soil, water well. Then, I put mine in the unheated basement where temps will range from 45-55 degrees. Maybe your garage has similar temperatures. After 4-6 weeks (we are faking a winter on them), the roots should be coming out of the bottom of the pot and the new shoots should be coming out the top. Bring a few into a bright room to green up and flower. After they flower, cut off the flowers and treat as houseplants until the leaves die off. Then, out to the garden with them.
