Found near a beach in Florida Keys. Searched drift seeds info but couldn't find it. Now it is starting to grow at top. Should I plant it? Any ideas?

Neat find and I would plant it in a nice size pot to be able to keep a close watch on the progress. Whatever it is, it must be pretty hardy to survive being in saltwater.

Good luck,
Thomas

My guess a palm seed of some sort. Many palms try to spread their seed by using ocean currents. Gene

Looks like Dioscorea bulbifera. (Invasive, air potato.)

I agree with Tiffany, looks like Air Potato (Dioscorea bulbifera) a very invasive vine! It's listed as a Category 1 Non-Native Invasive here in Florida. You can see more photos of the leaves, bulb/potato on these pages:

After reading about this "thing", I would like to amend my first advice and say BURN that dude!

Aw, put it in a pot where it will be confined and see what it grows into.

Tiny chuckle here....had one once and managed to kill it person who gave it to me was amazed.

Wow, I didn't think anything would kill those things!

I agree it looks like the Air Potato. I had one growing in a pot...it escaped and invaded the Four O'Clock bed...it reached out and climbed the Sycamore tree (do you know how tall the Sycamore grows?)...and out of spite, the Air Potato dropped a huge "potato" on my head.
Ouch! Not only are these plants thugs, but they are inconsiderate of unsuspecting humans.
