This fancy fellow is a terrific xeric garden plant. It's showy, well behaved, and requires practically no attention. It grows low to the ground as a leafy rosette, and the blooms are nearly at ground level. The large pale flowers open at dusk and last a single night, turning pink the next day before fading completely. Like many evening-primroses, this one is pollinated by moths, important pollinators we tend to overlook.
This is a low water plant. It will not tolerate things like sprinkler overspray. It likes thin rocky soil and full sun, and will do great in a sunny rock garden or even in that crummy area next to the sidewalk.
