Cultural Significance
White Prairie Clover is a keystone prairie species and was formerly classified in the genus Petalostemum (meaning "petals with stamens," referring to how the stamens and petals are connected). The genus Dalea honors Samuel Dale (1659-1739), an English botanist. The species name "candida" means white in Latin. As a nitrogen-fixing legume, it plays a crucial role in prairie ecology by enriching soil. Its presence indicates high-quality prairie remnants. The flower's unique blooming pattern creates a distinctive white ruff that slowly moves up the spike.Shop Our Floral Collection

Frequently Asked Questions about the White Prairie Clover
Is White Prairie Clover the same as Dutch White Clover?
No, White Prairie Clover (Dalea candida) is a native North American prairie plant that grows 2-3 feet tall. Dutch White Clover (Trifolium repens) is a low-growing European species commonly used in lawns. They are not related despite sharing the common name "clover."
Why is White Prairie Clover good for prairies?
White Prairie Clover is a nitrogen-fixing legume that captures atmospheric nitrogen and makes it available to surrounding grasses and plants. Its deep taproot (up to 5 feet) makes it exceptionally drought tolerant and helps prevent erosion.
How can I tell White Prairie Clover from Purple Prairie Clover?
White Prairie Clover has white flowers and 5 stamens, while Purple Prairie Clover has purple flowers. Before flowering, White Prairie Clover has wider leaves while Purple Prairie Clover has narrower leaves. White Prairie Clover typically blooms about two weeks earlier.
Can I use White Prairie Clover for erosion control?
White Prairie Clover is slow-growing during its first year and takes about two years to mature, so it is not ideal for quick erosion control. However, once established, its deep taproot makes it excellent for long-term slope stabilization in prairie restorations.
