Question: We have a plant in the yard (North Idaho) with orange berries that sure looks like the pics of Western Mountain Ash which is supposed to be great for jams and jellies. The leaves also look like the pics of mountain ash. Is there a poisonous look-a-like to this plant? We want to get making some preserves if we've got the right berry.
As far as I know there are no poisnous look-a-likes to mountain ash, except for mountain ash...the leaves and seeds can contain a small amount of cyanide so be careful with those. Other than that you should be good to go. Don't forget that the berries also can be made into a pretty good wine!
