Desert thorn-apple is an annual wildflower that produces large, showy white trumpet-shaped blooms from late spring through fall. This native plant grows as a bushy forb with broad leaves and can self-seed readily in suitable conditions. The flowers are fragrant and open in the evening, making it particularly attractive during summer evenings.
