I pinched this off of a palm tree in Florida.  It grows on the bark as seen in the picture attached. I've had it in a vase of  water over a month thinking it'd grow roots. The root looking thing (in the picture) was like that when I pinched it off the tree. My goal was to plant it in a pot in Ohio as an indoor house plant….But with no roots, can I? Will it die in potting soil with just that one root looking thing? Will it grow in potting soil or the fact it hasn’t died already (and lives off the tree bark in FL), is it more like an air plant? Or should it remain in a vase with water for the rest of it’s days? Will it grow in just water? How much of the stem needs to be touching the water?  I'm shocked it hasn't died relying solely on water.  Is it a philodendron? Look how wide the stem is.
