The plant is ALWAYS a short height, pruned or not. It does not make tree lists usually.

Prune away...

Far as I've read, Zone 7B is too hot.

It's going to be in shady, moist, cool woods.

Why is it so hard to find this plant??? I've only found a couple online and they've been gallons when all I want is a small one.

There's no way I'd be able to find it locally.

It isn't considered to be that ornamental. It is native to Canada, Zone 2 to 6 listed in books.

How about Cephalotaxus harringtonia? It is similar but likes heat and shade, you can get upright and low cultivars.

Do you see many Taxus/Yews where you live?

I see hundreds of Yews everyday, you no longer even notice them.

I really want it partly due to the fact that it's a native to the US.

Ah. Thats part of the reason i want one... but of the yews it is likely the least ornamental. No one really grows Florida yew, but... that might be a better bet for you. IF you could find it... probably not. If you could find both i would give them both a whirl.

The pickiness of site and general lack of ornamental attributes is why taxus canadensis is rarely sold.
