Good Companion For Hazel Trees

alfharris8

We have an area of garden that is a little space of it's own and was planted with native trees about 30 years ago.
Ash were the ones that grew dominantly but now due to die back we will soon have to fell them leaving about 5 hazel trees and not much else.
Looking for inspiration for what other trees / shrubs would make attractive companions for what remains. 
Not fruit trees. Thanks.

If you want native maybe hawthorn,  or exotic flamingo willow. For bushes how about dogwood ( nice winter coloured stems) or maybe ferns if it's damp enough, depends what you like and the conditions of the soil @alfharris8

I'd go for Guelder rose https://www.woodlandtrust.org.uk/trees-woods-and-wildlife/british-trees/a-z-of-british-trees/guelder-rose/, along with the dogwood.
