There are different kinds of daisy trees. Some are perennial, and you can plant them in the ground, but some are not. The ones that are not will not tolerate temperatures lower than 40 degrees. If there was a tag on the tree when you purchased it, that should tell you what temperatures the plant can tolerate. If you know the scientific name for the plant (which should be on the tag) you can look it up on the web for more information. If you don't have the tag, maybe you can go back to where you bought it and read the tag.
