A compact coastal shrub with fine, feathery foliage and bright yellow daisy-like flowers that bloom in late summer and fall. Extremely drought-tolerant and salt-spray resistant, making it ideal for coastal gardens.

Why grow it

Coastal goldenbush fills a practical niche for gardeners managing exposed coastal sites where many shrubs struggle. Compared to other salt-tolerant ornamentals like coyote brush or California buckwheat, it offers finer foliage texture and reliable late-season flowering when other plants are fading. Its compact habit and minimal water needs once established make it suitable for water-conscious landscapes in maritime climates.

Watch out for

Plants may become leggy or decline in vigor if grown in heavy shade or poorly drained soils, despite their drought tolerance. In mild coastal regions with consistent fog, monitor for occasional fungal issues on crowded plantings, though this is rarely severe. Deadheading spent flowers can extend bloom and maintain a tidier appearance, though the plant will self-seed modestly in ideal conditions.
