Rhus typhina stag's horn sumach, very pretty colour changes in the autumn but can be invasive.

Also, if you gently lick the flower...it tastes of sherbert (Alan Titchmarsh tip there)

Thanks to you both. So the fruit is edible then?

I never knew that Andy and I grew one for 12 -15 years lol. Thats what I love about these questions always some interesting titbit,
There will be very little flesh on one fruit and very sour, apparently the leaves are rich in tannin so if you have any thing to dye Ad44?
