(Syn.: Deilanthe thudichumii) This delicate succulent features fleshy, fuzzy leaves and strikingly large, bright yellow flowers that unfurl in the late afternoon. Blooming between 3 p.m. and 9 p.m., the flowers open at twilight, creating an enchanting display. Its evening rhythm and fragrant blossoms make it a prized choice for collectors of nocturnal bloomers.
