looks like Livistona chinensis (several of them)

Excellent

Thanks lzddr

So this is one of the less hardier palms I take it.
Probably the best option for me now since it's in a pot would be to bring it indoors?

Is it okay if I remove some of those other starts?
I can take it inside only if I reduce it's overall size

Yes, this one needs to be brought indoors in most zones.

They are grown from seeds, which are planted in clumps to allow the pot to fill out faster for the grower, and make a bushy looking plant. But in nature, they would grow individually into a tree. They are not naturally a clumping palm.

You could try to very carefully separate them if you wished, but I think you'll find it harder to do than it looks, as the roots are often completely interwoven. Or, you can just sacrifice some of them by cutting them off below the soil line.

But personally, I'd leave it just the way it is. CFP is actually really easy to grow as a houseplant, and should do fine. I winter mine in quite cool conditions, generally between 45-55 degrees, and not in very bright light, and it just sits quietly and sleeps until spring, then grows nicely again all summer.

They are pretty cold tolerant, but not really worth trying to protect in a zone 5 since they can only handle low 20s. Mine have survived light snow and low 20s and do begin to turn a dark green color, and eventually a temp like 20F take it out. But Im trying one in the ground this winter with protection and Im looking forward to seeing how it does! I plan on protecting it when temps go below 25F and never letting it see below 22 or 23. I would definitely bring yours inside because its a beautiful healthy plant.
Also windmill palms are SOMETIMES called Chinese fan palms, but its used really rarely and isnt a common name for it. When I hear Chinese fan palm, I definitely think Livistonia right away. One of the many differences between a windmill palm and a Livistonia is that livistonias have spines on the petioles. The "fans" are also less divided and very different in shape from a windmill palm. Windmill palms also grow a little faster than most livistonia species and have a wooly trunk, unlike livistonia.
Good luck!

Great
Thanks for the feedback guys.
I will definitely bring this guy inside for the winter. I may attempt to remove some of the smaller plants but your right that may be difficult, the stems are pretty rigid and those thorn looking things are definitely imposing!

One other tip for you. Buy yourself a spray bottle of Wiltpruf anti-dessicant spray (most any nursery should have it, or HomeDepot/Lowe's should have it shortly, when they start carrying cut Christmas greens).

Spray the entire plant thoroughly with Wiltpruf, especially the undersides of the leaves.

It's one of the best ways I've found to control spider mites. It's non-toxic, a waxy substance made from pine pitch, actually. It suffocates mites and makes a long-lasting coating on the foliage.

I do almost all of the houseplants with Wiltpruf when I bring them in. You can't use it on succulents or things with hairy leaves, but anything with a glossy or hard leaf, it's great.

Excellent
Thanks again I will definitely be on the look out for some Wiltpruf

I thought I would post a follow-up here since I got so much good information. Surprisingly this chinese fan palm did pretty well indoors this winter...even put out a few new fronds/leaves. I did not get around to splitting it, figured it would probably be best to attempt a little later this spring. I actually took it from a 24" pot to a 10" pot which was basically just all roots so not sure if that helped at all. My question now is...I want to put it outside. How long do I have to wait. Normally with my houseplants I wait until night time temps are consistently in the 50's. Right now we're ranging 40-60 degree night time temps. I realize if I did put it outside and we had a night dip into the 30's I would move it back inside.
Let me know your suggestions!

Thanks

Common name... Chinese Fan Palm.

I think its safe to keep it outside now. Just make sure that it doesnt see below 40F. I protected mine outside this winter and it had no damage at all! But then it did end up getting some minor tip damage because I took its protection off too soon and it saw a 21F night. But its a very frost tolerant plant and even though I wouldnt recommend letting it see a frost, it can handle it with no problems! Your palm is looking great! Thanks for the update! They are great indoor palms and really dont mind being ignored.
Good luck!
