Take it out of the pot. It'll likely be a ton of little plants. Plant each one in the gravel. Crypts are notorious for "melting," or losing all their leaves, if the water parameters in your tank are are different from the ones at the store.

One thing-either dip it in a very very very weak solution of either POTASSIUM PERMANGANATE or PLAIN bleach before putting it in your tank. Trust me, you'll thank yourself for doing this. It's really easy for your tank to become overrun with snails that you get as "gifts" when buying plants.
