A little green

Every time I've visited a new nursery in the last few years I've inquired about these trees. A ficus of sorts that has a big green leaf and grows happily indoors given enough light. I first saw them in LA in a furniture showroom and even though they were planted in pots they had grown up and into the vaulted ceiling. I've never found one at a nursery in South Africa but I see them growing on the sides of the road like weeds. So tempted to don my balaclava in the middle of the night to go dig one up.
