Oenothera speciosa (Pink Evening Primrose) is a hardy, semi-evergreen perennial that forms extensive colonies with showy, cup-shaped flowers that range from dark pink to white, lined with pink or red veins. This drought-tolerant plant grows up to 2 feet tall, thriving in full sun and well-drained soils. Blooms appear from February through October, with southern populations opening their flowers in the morning and northern populations at night. It is commonly used as a groundcover in sunny areas, attracting birds and serving as a nectar source for pollinators.
