Okay, now that I'm positive of what plant we're both talking about (doesn't matter the green or the variegated) I can tell you some things about it (them).
#1) Tougher plants are hard to come by. Tough, tougher & toughest. They're hard to kill.
#2) They don't mind being super pot bound.
#3) They can successfully be grown indoors without a lot of hoo ha.
#4) They are very forgiving of "I forgot to water them".
#5) You want more of them? EASY. Sand, just moist not wet sand, stick cuttings in. New plants. They *do* take a while though before they show much growth at all but when they do, they take off!
I had one of these in a pot -- the SAME pot --- for 24 or 25 years. No kidding! I am a Fl. native but we had moved to Tn. for a few years. In south Fl. these grow outdoors in the ground or in a pot, either way. Anyway, I got one when we were in Tn. & it lived in the house quite contentedly. One of only 2 house plants that I couldn't kill. My green thumb only applies to outdoor plants.
We moved back to south Fl. & it moved with us & stayed in it's pot. Several more moves down there & then we built a house where it had it's new home on the front porch in the very same pot. No new soil, just the same old pot, the same old soil. They can take full shade or full sun. The same plant. If you move it quickly from 1 to the other, it will lose it's leaves but the roots will still be alive & eventually it will sprout out with new foliage. You can cut these back HARD. You can cut them back so hard there are only stems left & they will grow new foliage. Did you know that if they get old enough or grow enough, they will send roots off the stems? You can actually add soil to the present pot & it won't kill it unless you keep it *too* moist until it sends roots into the newly added soil. You can cut it back as far as you wish, give it a bright spot in the house & decent water & food over winter & I'll lay odds it will have new foliage before you ever move it back outdoors. BTW, they *can* take pretty cool temps. but not freezing. It lived outdoors through a cold winter in north Fl. when we even had frost. I was as shocked as anyone that it could take those temps. & never miss a beat.
