Sun Requirements: Small sundrops thrive in full sun and requires at least 6 hours of direct sunlight per day to flower well. In partial shade, it will still grow, but it may produce fewer flowers.

Soil Requirements: Oenothera perennis is adaptable to a wide range of soils, but it prefers well-drained, fertile soils with a slightly acidic to neutral pH. It will not tolerate waterlogged soils, so it's important to choose a location with good drainage in the garden.
