A deciduous California native shrub with maroon-red flowers that emit a spicy fragrance from late spring through early summer. It grows as a multi-stemmed spreading shrub and prefers moderate water in well-drained soil.
Why grow it
Western Spicebush offers a California native alternative to Eastern Spicebush (Lindera benzoin) for gardeners in western regions, with the added ornamental appeal of deep maroon flowers rather than small yellow ones. Its extended bloom period from late spring through early summer and notable fragrance provide sensory interest across multiple seasons. The species tolerates moderate summer water rather than requiring consistently moist conditions, making it adaptable to a range of garden settings with well-drained soil.
Watch out for
This shrub can take several years to establish a full, multi-stemmed form and may appear sparse during early growth stages. In warmer microclimates or with excessive summer watering, fungal issues may develop, so ensure good air circulation around the plant.
