The Only Use for Mahonia

In recent years I executed a campaign to rid myself of Leatherleaf Mahonia in favor of useful native shrubs.  I got rid of all of them save one, which is doomed.  It seems to have one use and that is an attractant for Gray Catbirds, and others, that seem to enjoy the succulent fruits.  This feeding frenzy is amusing.  But on the flip side, the lousy berries are ultimately turned into plants that I will have to hunt down and eradicate.  Maybe this season the last beast will go and this could be the last time I'll watch Catbirds go ape for fruit, at least until the replacement plants get old enough!
