That's an incredibly tall Sans there Skylark!
Presumably the door is to show scale, which is does nicely, but I'll bet that you don't grow the plant in a doorway
I am curious how tall these plants can get. I have one that is about to touch the ceiling, but it is only about 5' tall residing on a cabinet. Will it stop when it reaches the ceiling? or what? Does anyone know?

I've seen them to 4 feet tall in-ground here in Florida. Great growing @skylark!

oh, thanks! the door was my ploy to show off ;)).. it's 48" at the tallest. but i have another pot with mixed S. trifasciata and S. trifasciata 'Laurentii' that has not been repotted in oh... may be 10 years? the longest plain ones are 61". it's in a 12"x12" pot.
it is my understanding that the longer you keep them growing without repot - the longer they might get. uppotting to a larger pot size is OK though. the one in the 1st pic was in super small 6.5" pot for around 10 years too.
also when you do not divide them, every new shoot gets bigger an bigger - they grow in a cluster connected by stolons.
once the shoot blooms, it stops growing (i have not measured myself though, may be it's NOT true?). and it takes 2-3 years for it to bloom from emergence.
they get partial sun in east or west window, which is pretty good. they'll take full sun indoors though.
if you want them to really grow they need good light and warm temps (over 75F, preferably to 85F) year-round.
the 1st plant is the product of mixed-up mama ;). here's a pic of it from DB

Just love these plants. Nice to see everyone else's plants. They can live forever, one of mine is 30 years old.

Here's my plain green S trifasciata. About 3 feet high.



One of my S trifasciata laurentii has a leaf which is 41 inches high. That new leaf is going to be massive!



I read somewhere once that if the pointed tip of the leaf is damaged it will stop growing.

I move mine twice a year the past few years (into the ground in spring, back to pots for winter,) and they get that tall. I think about 5 ft. would be the max under any conditions.

Here's a pic from about 20 yrs ago, the pot was about 8" tall. I think this is about 3 yrs in the same pot when I took this pic. Plants have been moved & repotted countless times since.

Thanks all
Here is a quick and bad pic of mine (didn't feel like cleaning the spider webs off the ceiling and everywhere else, rearranging, and fixing the lighting problem with so much outside work to do today. Please excuse the spent paperwhites and other junk.)
The tallest there--about to reach the ceiling is 51 inches.
That's a north window.
The plant had been in a tiny square pot (6in) in a very dark place for about 10 years. When I moved, it got this window and grew enough that I thought it may break the pot I repotted and it bloomed and took off growing! Also--no fertilizer, then, or ever and that was just cheap, un-enhanced potting soil.

I am hoping it will hit the ceiling and just stop already

How tall are they by now?

about the same
I have three leaves now just millimeters from the ceiling and even more spiderwebs

Hi Dirtdorphins
What species is your plant please I'd like to get one

Hi Gee99 to NGA
I think my plant is S. trifasciata laurentii, on account of the yellow margin on the leaves
Mother-in-law's tongue (Dracaena trifasciata 'Laurentii')

in case anyone is wondering, the bulk if it now resides on the floor in a darker place and the tallest leaf is 56inches the rest of it is in a different pot at that window working on reaching the ceiling again

I really should just get one! Love yours DD, with those yellow edges!

It's a great plant Suzanne, give it a try

I should really take a better picture

My plain S. trifasciata on the kitchen isle did hit the ceiling, so was about 55" from pot. It was one single long leaf among all - looked weird.
then i put it out on the balcony for summer and that longest leaf bent sideways and was unmanageable. So i trimmed off the top - once they bend there's no unbending...and then i gave it away, since i needed room for other more exciting plants.
I finally re-potted that big pot in the pic of S. 'Laurentii' , ripped out all the plain shoots. and put the left-overs in a smaller pot. it has several older leaves at 48-49". the oldest really long ones were bending and i trimmed them off by a couple feet.
