My website says:
"This plant may be as close to the perfect houseplant as you'll find. Ficus 'Benjamin' drops its leaves constantly and grows leggy. Ficus 'Fiddle Leaf', though a grand plant like no other, grows very fast. The 'Alii' has all of the best attributes. Unlike the Fiddle Leaf, the 'Alii' grows only approximately 6" per year and unlike the 'Benjamin', the 'Alii' seldom drops leaves and grows more densely. Though the 'Alii' grows best in bright, indirect light, it tolerates less light. It also tolerates neglect and can go periods without water or fertilizer. It can be pruned on a regular basis to not only control its size but also to increase density.
IF YOU HAVE LIMITED SPACE OR JUST WANT AN EASY-TO-CARE-FOR PLANT, THE 'ALII' IS JUST THE PLANT FOR YOU."
I rooted divisions of a four year old plant last summer and posted them on my website (for the first time) in the early fall. I only had three rooted divisions and quickly sold them all. I am rooting a few more divisions but they won't be well-rooted until spring. Rooting and air-layering divisions of my ficus plants, both 'Alli' and Fiddle Leaf, takes so much of my time that I don't do this often. I never keep those rooted divisions long.
