Hi elfybois,
to the site!
What a lovely
Anthurium (Anthurium clarinervium) and I agree with Gina that you should find a slightly (just slightly) larger pot to plant it in. Don't try to disentangle the roots because that would likely cause damage and undue stress to the plant. Place a bit of soil into the new pot so that the plant will be sitting at the same level as it was in it's original container; place the root system down on the soil and fill in around the sides, gently tamping it down to secure the plant in it's new pot.
