Hi Amber
Good to see you
I have a rubber tree plant that I have to cut the top off every year because it's gotten so tall. It's currently 8 ft tall,, and doesn't need direct light and they grow fairly fast.
Also a ficus gets really tall.
Janet Craig will grow tall --->
To add "texture" a good sized Pencil
cactus to start out with can grow really tall, . I had a pencil
cactus that once reached 7 ft.
and the Milk tree
cactus gets tall and gives off yellow waxy star shaped blooms near the trunk,, these seem to grow slow then suddenly shoot up 6 inches at a time,
Mother in law tongue( snake plant gets tall,, ) as well, ( in the same picture with the rubber tree above)
