Antarctic pearlwort, a low-growing shrub with characteristic yellow flowers, is one of only two native flowering plants which occur in Antarctica.

These remarkable little plants manage to thrive in one of the harshest climates on Earth! With their resilient nature, they play a crucial role in the fragile Antarctic ecosystem, providing an essential source of food and habitat for local fauna, especially for tiny invertebrates and migratory birds that rely on the sparse vegetation during their visits.

Did you know that the study of Antarctic flora could offer insights into climate change? Scientists are closely monitoring these resilient plants to observe how they adapt to rising temperatures and shifting environmental conditions, which can help us better understand the impacts on global ecosystems.
