Fun Facts

🌱 The name 'Crossandra' comes from the Greek words 'krossoi' (fringe) and 'andros' (male), referring to the fringed anthers in the flower.
🌱 Dwarf Crossandra can bloom almost year-round in warm, consistent conditions, providing continuous color for many months without dormancy.
🌱 The plant produces seed pods that explosively dehisce (burst open) when ripe, dispersing seeds several feet away—a trait common in the Acanthaceae family.
