Skunkweed (Navarretia squarrosa) is native from California to British Columbia and also Nevada, and can be found in a wide variety of habitats, including grasslands, coastal dunes, vernal pools, and disturbed sites. If you have the nose for it, Skunkweed is really a rather charming plant, with its profusions of tiny blossoms that range from lavender to periwinkle in color.
Skunkweed typically flowers in the spring, from April to June, the profusions of round flower heads forming whimsical mounds before blooming. The flowers attract a range of pollinators, especially bumblebees, small native bees, and butterflies. The flower heads provide a good feeding platform for these pollinators as they comb them over for the little nectar-filled blossoms. Skunkweed is indeed a pungently aromatic plant; however, the aroma is produced by the foliage and stems, and is only particularly noticeable when plants are disturbed or heat stressed.
Skunkweed thrives in both damp and well-drained sandy or sandy-loam soils, though it can tolerate a range of soil types, including clay and even dry gravelly soils. For germination, Skunkweed seeds can be sown directly onto prepared soil in the early spring. Well-established plants are also very tolerant of transplanting from containers pre-bloom.
