Every winter I am on the Oregon trail for garden scent. My best hope is the Mahonia (aka Oregon grape) which grows very well in various shady parts of my garden and flowers profusely in winter. Regrettably I find the much acclaimed scent is hard to detect but smell is not the only thing that gets up my nose! The rigid leaves have several vicious points on the arrayed leaves and catch me out many times a year. This is partly due to a 6 foot shrub near my Japanese garden path. I don’t know what made me think Mahonia was suitable in a Japanese garden but there you go. As a deterrent to uninvited visitors the prickles make it as good as Holly and a close second to Berberis.
The stems or branches are an interesting yellow colour but only get seen when pruning. I prune or trim regularly which aims to keep older plants in shape. Other maintenance is minimal as no critters would make a meal of the leathery, spiked leaves.
