I think Schefflera is an aquired taste that I've yet to aquire. I have a hard time appreciating them. I have a couple but nothing I can get too excited about. However, I think the nebari on this one is better than a lot of ones I've seen. I like the last photo the best.
Realistic cascades are hard to pull off, which is why you see so few really good ones. This species will present some challenges to you in this style but I like the idea, keep us updated please.
