It’s Latin name is Rubus spectabilis.
Around here it is known as “brush”. It is used as a stream or river bank stabilizer because of it’s mat like root system.
It’s berries, yellow or red, are edible as are the spring shoots. I haven’t tried the shoots, but the berries are good. Some years sweeter than others but most of the time kind of flat or bland tasting. Very seedy.
It likes moist to wet areas. Found in most logged or disturbed forest areas. Can grow to eight feet tall.
