I agree with eclayne .... the plant in question looks to be Philodendron bipinnatifidum You should be able to plant it in the ground here in central Fla. I live on the east coast of central Fla. in Daytona Beach and they grow in the ground here. Winters with frosts or a hard freeze will leave them looking pretty pitiful for awhile but if they have a decent layer of mulch to protect the roots, when warm weather returns they will sprout new growth.
Earlier this year we sold the house that we'd owned for 40 years where these were growing. I miss my tree Philo's!
