I'd ask for a recommendation from a experienced southern CA gardener - rather than a rampant hosta-phile from the Great White North. Some things just don't transplant well... With proper care (watering, maybe some shading, good site prep) you should be able to put that little Fig right in the ground. As no one else mentioned it: Maple species will have opposite arrangement of foliage, whereas your Fig should have alternate arrangement of simple leaves. Shape of the leaf should almost never be your first clue on plant ID.

Do you have an oak tree near by? It looks like what's popping up in my yard. Susie

That's ok, I figured that's what happened. I had two of those nightshades growing in my potatoes and wondered if I had planted something for awhile.

said in your tree sapling ID post... a free plant.. usually .. most of the time.. rarely turns into a valuable plant ... and when you find the 100th one.. you will know why .. lol ... in this post.. the only thing i see of value.. is the vinca .. periwinkle ... ken
