You could trim now but that would probably encourage it to grow some more. Either way you'd probably have to trim it in the spring, but you could always root the cuttings and or leaves and have more for trades or just stick them back in the pot for a fuller plant. It's really up to you. I would try a leaf cutting just to experiment. Lay the leaf down and do a few cuts through the veins then lay it in moist perlite, cover the container with saran wrap or a plastic bag and each cut will produce a new plant.

I am terrible at leaf cuttings, several attempts with my Rex Begonia. I have a great begonia I still need a ID on, will post later. Petiole leaf cuttings have been successful for me, authough that's a rhizomatous begonia, this is a cane begonia

Scroll down to the bottom on the ink, it covers all sorts of begonias.

Thanks, I didn't notice the link, will look now

I have much better luck with Begonia cuttings in the spring. When you cut it, the stump will probably grow a new top, and there should also be some new shoots from the roots soon after cutting. Since new canes grow so readily, I've given up on leaf cuttings for these. None had worked for me anyway, though I admit I didn't try many.

Is that 'Corallina de Lucerne?'

That's what I thought, hearing you say it is a confirmation. It produces lovely bunches of flowers! Back of leaves are a lovely reddish color. VERY strong grower

It's a beautiful healthy plant. I just never had good luck with them.

Wow, that is really etiolated. Don't know that I would bother cutting back until days lengthen to where you can provide better light.

The plant just got done flowering, I don't think is light starved exactly, especially because the lower stalk is compact and the tall stalk is full. Its in a decently bright window, basically the minimum to maintain such a plant

How is this plant doing now?

I decided not to trim it. Its at school right now. It has been getting very lanky...

The days are getting longer, that should help. Good vibes!

When you prune, it should be cut back to very close to the soil line, with a sharp tool, and just above a viable leaf, so you remove ALL the exceptionally long internodes. If you prune it now, you remove most of the plant's ability to make food; + the growth that occurs after you prune it will still be lanky, so you're right back where you started. If you wait until mid to late May to prune, the plant will have much more reserve energy (than if it was pruned now) and all new growth will be compact - which is what you want.

In plants where internode length plays a significant part in the plant's appearance, it's best to get in a pruning rhythm whereby you get to keep only the growth with short internodes and remove the growth with long internodes. You do that by pruning in late spring (early to mid-June) or early summer, just after the summer solstice.

We all want healthy looking plants, and there is no law that says we must retain every little bit of growth the plant puts on. Part of the grower's growth comes from learning ways to ensure plants are healthy and attractive. Leaving behind the feeling that all growth is sacred and deserves to remain on the plant is a step forward on the path we're all following.

Thanks Al! Yea. I definitely needs to be trimmed, but I totally agree I should wait. I'll put if outside and give it a nice trim and summer vacation

Thanks for the vibes. I feel spring

Please put it in a shady spot if you're going to put it outside for the summer.

What's the desirable length between nodes on an angel wing?

zzackey, I usually plant it among other annuals in part sun, and they seem to like it. Of course at first a few leaves burn, but they always recover. The winter time is tough for my plants

Gardenfanatic, depends on the particular cultivar.

You could probably get away with that in Albany, NY. I'm alot closer to the equator than you are.

True, but don't doubt just how hot and humid it can get here during summer. But I'm sure Georgia is much worse, lol
