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.
