The flowers are yellow and quite fragrant which attracts pollinators during the spring. The berries are a great food source for birds and mammals during the summer and fall.  Since it is an evergreen shrub, it provides foliage cover for small animals during the winter months.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Ethnobotany<\/h3>\n\n\n\n<p><em>Mahonia nervosa<\/em> and <em>M. aquifolium<\/em> contain alkaloid compounds including berberine which has been used for medicinal uses supporting immune health and strong antibacterial properties.
