Common Draba

<em>Draba verna</em>, the common draba, is a small annual flowering plant in the family Brassicaceae. This species has a broad global distribution, occurring across Asia, including Japan, several European countries, North America, Oceania, and South America, where it typically inhabits diverse terrestrial environments such as dry grasslands, rocky outcrops, disturbed ground, and coastal sands. Common draba is among the earliest spring wildflowers, typically blooming from late winter to early spring. It is characterized by a basal rosette of small, slightly hairy leaves and slender stems bearing tiny white four-petaled flowers clustered into a raceme. <em>Draba verna</em> usually grows to only 5–20 centimeters in height and produces small, oval seed pods. The species often colonizes open, nutrient-poor soils and can be found in disturbed habitats including lawns and pavement cracks. It is assessed as Least Concern, reflecting its widespread occurrence and adaptability. Biological traits of this species, while not extensively studied in detail, are broadly consistent with other annual members of the family Brassicaceae.
