We love the winter hardy Chinese schefflera, Schefflera delavayi. This smaller and hardier version of the small tree that’s planted throughout central and southern Florida, is reliable for us here in Zone 7b. Here’s an image taken just prior to our first hard freeze. It’s been a few years since we got viable seed, so fingers crossed for this year.

I have one still going strong in Summerfield NC after several years!
Excellent!
