From what I've read, I should be able to cut the top off and plant it, and it will grow. However, I've only been really working with plants for a year or so, so I'm not exactly sure where to cut it.
Also: I'm so sad this has happened! I just got the plant and intended to re-pot it.
I'm going to try to add photos. In second photo - is that focal point, at that leaf node, the area I should cut it at?

To propagate Ti by stem cuttings you have to have the 'hardened off' part of the cane where the leaves have already fallen off. Then you cut the cane into pieces and lay them in a pan of soil half covered. This is called the buried cane method. The part of the Ti cane up where yours is broken probably will not root, it is the softer actively growing part. You can leave it alone, or, if you choose to cut it off, new shoots should sprout out of the cane just below where it gets cut off.

Thank you for your answer, Gina. I hate to leave the plant tilted like it is, but hate to lose that growth, too. *sigh*

Bright Colors, a hungry deer just ate the top of my favorite Ti so I understand how you feel. However, they are very forgiving plants and yours will do just fine.

Scott shared a unique method of rooting Ti's with me a while ago. He cuts the stem, like Gina mentioned, on the hardened section, lets it dry or callous for a few days then puts the cut section in a container in about an inch and a half of water, no more than that. I tried this and it is amazing, roots formed within days. Scott, if I have this wrong please chime in.

That sounds like a great way to root Alice. I always used the buried cane method because it yields more plants than just one LOL, I was propagating Ti to sell. I had no idea deer would eat Ti....I have mine outside the greenhouse (I put them out every summer) because inside they are just mealy bug magnets. We have a ton of deer so far they have left them alone fingers crossed

I always had some buried canes going as demos for my propagation classes but for a mature plant instantly Scott's method worked for me.
I guess it could have been a rabbit that ate the Ti. The damage was up pretty high but rabbits can climb.

I have a friend not on this forum, he lives about 6 miles from me, and he cannot grow any ginger except COstus in his yard. Every other genus he plants get immediately mowed down. He suspects squirrels, but I have literally hundreds of hedychiums, curcuma, zingibers, costus in my yard, and we have deer, raccoons, squirrels, rabbits and opossums, not to mention wild pigs, and they have NEVER touched any of my gingers. I told him to get a motion activated camera to catch the culprit.

@BrightColors
Have no fear! Your Ti will repair itself in time. Just remove the broken growth and discard. A new growth point or points will emerge to replace the broken out growth.
Here is a look at a Ti that also experienced a broken growth point. Notice that the one has been replaced by two.

Thanks to everyone for the replies!
I think I've got a way to help myself feel better about cutting off the broken top; I bought another Ti plant, with the idea of just planting them together. Maybe they'll compliment eachother.
Anyone have advice on what kind of planters these plants like? Short, tall, shallow, deep? When I see them in planters, the planters usually look not very big (but not too small).

I've been growing Ti's in containers for several years now. They are great container specimens and I've learned a few things about them.

They are an understory plant and while they do well in pots of about any kind as long as it has good drainage, they also do perfect in the ground. I don't know your zone, but I think they would be just fine.

Mine are continually getting ravaged by the strong winds, and too much evening sun, but they are troopers. I just trim off any damaged leaves and it makes the plants more prolific.

They will get frost damage if you live in a frost area, but again, they can be trimmed down and they will come again. It's amazing.

I have mine in large square plastic pots and I have English Ivy all around them trailing down the sides. No camera here, sorry.

Ohh, thank you, slowcala! I'm going to try to keep these inside, in a pot, until I can get some other baby Ti plants from them. Then I might try them in the yard. We get weird weather. Not much for getting snow, but we get frost that lasts for weeks, and kills everything but the weeds and the bugs. Haha

Another problem I've had is the way we get 2 weeks straight of heavy rains. I've lost so many plants because of the rain. Sometimes, I have to bring certain plants inside, just so they don't stay soaking wet for too long. Having issues with a Persian shield right now, because of that. It wants to be outside but the persistent rain seems to annoy it.

Hey everyone! I just wanted to update: when I went to pot my Ti plants, the one I originally posted about had righted itself! So, I didn't have to cut it. Yay!
