White four o'clock is a low-growing wildflower that produces small white trumpet-shaped blooms from June through September. The flowers open in late afternoon and evening, creating a subtle fragrant display in drought-tolerant gardens. This hardy perennial dies back to the ground in winter and returns each spring from deep taproots.
