This Ficus salicaria, older names include F. salicifolia, nerifolia, neriifolia etc., was purchased from Joe Samuels in 1983 as a rather small tree. It has lived with us since then as a summer patio plant or indoors under lights.
The aerial root on the right was created by grafting a rooted cutting into the lowest right branch of the tree. Ficus salicifolia will form aerial roots readily under humid conditions. Grafting allowed me to place the aerial root exactly where I wanted it as contrasted to allowing nature to dictate where an aerial root might spontaneously appear.
It is currently 23 inches tall with a trunk of 2.5 inches.
