Alsodeia Semigyrata

Common evening primrose, scientifically known as Alsodeia semigyrata, is a striking member of the Oenotheraceae family native to the arid regions of the southwestern United States. This perennial plant is recognized for its vibrant yellow flowers that bloom at dusk, attracting nocturnal pollinators such as moths and bats. With its slender, branching stems and lance-shaped leaves, it thrives in well-drained soils and full sunlight. Despite its beauty, it remains a relatively obscure species, often overlooked in favor of more common flora. Its ecological significance and unique blooming pattern make it a fascinating subject for botanists and nature enthusiasts alike.
