My neighbor has a houseplant that we cannot identify. She believes that she bought this from Lowe's. I have re-potted this plant two times and it is growing rapidly and is very healthy. It is now about 56" tall. Can you help us identify this plant. I think it is some variety of an umbrella plant (Schefflera actinophylla), but the picture I found on-line is different from what she has. See photos attached. Since this plant is growing so quickly, we want to know if you can cut the plant down and how to do this. Can you please advise. Thank you. Colleen
