The World's Oldest Container Grown Indoor Plant

This Cycad, Encephalartos altensteinii, was first planted in a container by a horticulturalist at Kew Gardens when they were first established. It's most recent container upgrade was only a decade or so ago, when it was repotted into the crate in the front right of this picture. This cycad is at least two and a half centuries old. This is a composite of two photos taken from near the doorway. You can't step back far enough to photograph the whole thing unobstructed without using a very wide angle lens.
