Hi Becky,
What a lovely gift.* Unfortunately potted bulbs such as tulips, hyacinths and daffodils are usually treated as annuals and discarded.* These bulbs have been forced and, especially tulips, don't often return to bloom again.

Of course you are free to try.* Water as you did when they were in bloom.* When the foilage turns completely yellow, cut off the yellowed leaves and plant in the garden when you can work the soil.
For bulbs that will return year after year you can look at these sites.

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
