About
Androsace septentrionalis 'Stardust' is an evergreen perennial that develops dense clusters of lanceolate, medium-green foliage, reaching up to 6 cm in length. In late spring through early summer, it bears open umbels featuring white flowers with yellow centers, supported by stems that can grow up to 25 cm tall. Although this plant has a relatively brief lifespan, it readily self-seeds, allowing for potential regrowth in subsequent seasons.
About the genus
