This hybrid carries a specific human story: it was found and named for Arthur Menzies, a former supervisor of plant accessions at San Francisco's Strybing Arboretum, who sent the original seedling to Washington Park Arboretum in Seattle in 1961. Growing up to ten feet tall and six feet wide, it is a substantial presence in the garden, with compound leaves bearing numerous spiny leaflets that give it the bold, architectural quality shared by the best mahonias. The showy fragrant yellow flowers appear from fall through winter, emerging above the foliage in upright clusters at exactly the moment when such warmth is most welcome.

This cultivar stands apart from its close relatives in two practical ways: it is more cold-tolerant and it blooms earlier in the season, which extends the garden's period of interest well into the colder months. Blue-black berries follow in summer, attracting bees during the bloom and adding ornamental weight afterward. Grow it in evenly moist, well-drained soil with partial shade and protection from winter winds. Once established it handles drought and deer reliably, though poorly drained soils can bring on root rot, and spider mites and scale deserve occasional attention.
