About Virginia Spring Beauty

Claytonia virginica · also called Virginia spring beauty, Spring beauty · flowering

Virginia spring beauty is a delightful spring-ephemeral wildflower native to moist, rich woodlands and disturbed ground across eastern North America, producing small white to pale-pink flowers with distinctive darker pink veins from late winter through April. The plant grows from a small, starchy corm and naturalises readily in lawns, meadows, and woodland gardens, disappearing entirely above ground by late spring. The most important care fact is to mark the planting location, as the corms are invisible once dormant and easily disturbed. Virginia spring beauty is considered non-toxic to pets.
