[Wikipedia] Cultivation: Due to its attractive yellow flowers and drought tolerance, Crocanthemum scoparium is increasingly used in native plant gardens and ecological restoration projects. It requires minimal water once established, making it an ideal choice for xeriscaping in arid climates. Additionally, it helps support local biodiversity by attracting pollinators and other wildlife. When cultivating Crocanthemum scoparium, it's important to replicate its natural environment by planting it in well-drained, sandy, or rocky soils with full sun exposure. It is relatively low-maintenance and can thrive with minimal watering once established. Pruning may be necessary to maintain its shape and encourage healthy growth. (link added by Mary Ann Machi)
