Thank you, huggorm

Good suggestions from huggorm. Chicago's Morton Arboretum has a very nice C. fargesii. The bark is reminiscent of Acer griseum (Paperbark Maple) and quite outstanding. I've got a small seedling that survived its first winter and will hopefully be hardy over the long run. Deer seem to leave it alone, which is a real positive.

I've yet to find C. chinensis, and I'd appreciate someone pointing out where it can be seen in arboreta.

Gothenburg arboreta has it, if you ever happens to visit europe. Still pretty young tree though, so no rush.

Morton Arboretum has C chinensis according to this search:

They are more shrubs then trees. If you want a TREE, Turkish filbert is closer to that.

There is also a C. fargesii at the National Arboretum, next to the parking lot of the Asian Valley. I was looking for C. chinensis a few years ago but never found it.

Like Turkish filbert, C chinensis and C fargesii are both relatively tree-like, and they are both supposed to have good resistance to eastern filbert blight (EFB). Turkish filbert is variable in its resistance to EFB.

Lone Elm - are you enquiring because you want nuts? Or are you just interested in a nice looking tree?

Morton has C. chinensis? I was probably standing next to it as I was admiring fargesii. This is why I prefer visiting arboretums on my own. I find that most people, even those with at least some interest in plants, get fidgety after a couple minutes looking at a tree. I suspect I'm preaching to the choir.

floral,

What it would be as a tree is first priority, the nuts I would like too; though that means two. Shrub like would not interest me.

It is possible to graft a nut-producing cultivar on top of a turkish filbert trunk if you want it to be a tree with larger nuts

Just wondering, because I have 2 Hazelnut shrubs, both only about 5-6 ft tall, no hazelnuts ever in fall, just the shrubs leaves and never any nuts. I was wondering how many years it usually takes before there are a noticable load of hazelnuts/

One possibility might be they don't have a pollinator they like. Not much help, I know, but some won't make nuts together, and you need a different variety.

Ones that are too closely related won't set seed together. Name the varieties you have and see if anyone here knows what pollinates them. My experience is very limited that way, as I have several kinds all open pollinated. Try the PEI Soil and Crops Association web site and scroll down for hazelnut trials ....some pollination work is listed.

Mine are shrubs and exactly alike. I may just cut them down, they aren't good looking, and will likely never produce.
