If you're looking for a desert-native groundcover with serious wow factor, Tufted Evening Primrose (Oenothera caespitosa) delivers. This low, spreading perennial forms tidy rosettes of silver-green leaves and erupts from spring through late summer with stunning 3–4" white blooms that glow in the evening and fade to soft pink by morning. It’s one of those plants that quietly steals the show with minimal fuss.
Exceptionally well-adapted to hot, dry conditions, this primrose is perfect for rock gardens, dry borders, or naturalized native landscapes. It's not just about good looks either—pollinators love it, deer tend to avoid it, and its ability to thrive in harsh soils makes it a true hero plant for xeriscaping. Give it sun, space, and a little love up front, and it will reward you with years of luminous beauty.
