Fatsia japonica as a dieback shrub in zone 6?

[Ohiopalmloverz6]

I’m thinking of adding an evergreen sort of whimsical but also SOME native plant shade border of the neighbors yard. I am in zone 6a/6b in NE Ohio. It’s covered with trees and there shouldn’t be any sort of property line problems. I’m thinking of adding a Fatsia japonica. I read online that they can be used as dieback shade shrubs here if heavily mulched. This winter has been a bad one. A few nights of -9 and one even got to -10. Usually it isn’t like that though. This has to be one of the worst winters we’ve had in years. I want to know other peoples experiences with Fatsia japonica in zone 6 as a dieback shrub. Will they get somewhat tall? I want them to preferably be around 4 feet tall.

I don't have any experience in really cold weather, but my Japonica cruised right through 22.6F like nothing happened.  I'll probably try this one in some more spots in my 9b/9a borderline area.

I'm not zone 6 but my fatsia has seen multiple zone 7B to one 7A winter and does fine with damage some years.

It's good into z7 evergreen.

Cruise big box stores in fall and winter. Stock up on Rhododendrons. Mountain Laurel is good too, but tougher to find. You may have to buy it on-line.

I don't think you'll get enough growth out of in a year to make it worth your while.  They aren't the fastest growing plant out there.  The other issue is they start to put out new growth in late winter and if you get a frost it will kill it.   By late winter I mean late Feb early March, here in Houston it stated in January.  So you probably get frosts well into April or maybe even May.  It will likely start regrowing much later in your climate but I would think you would have to be protecting it for at least a couple of months each spring.
