Fun Facts

🌱 Aster Rosy Veil was developed through selective breeding to achieve its compact, mounding habit and prolific pink flowering, making it superior to wild aster types for ornamental use.
🌱 The name 'aster' comes from the Greek word for 'star,' referring to the star-like arrangement of petals radiating from the yellow center of the flowers.
🌱 Asters bloom when most other garden plants are fading, making them a critical food source for monarch butterflies during their fall migration to Mexico.
