Fun Facts
- 🌱 Leucadendron is derived from Greek 'leuco' (white) and 'dendron' (tree), though many species like Crimson Cushion display vibrant reds, oranges, and yellows that intensify in cool weather and stress conditions.
- 🌱 Crimson Cushion was selected and bred specifically for its compact habit and intense coloring, making it more garden-friendly than many wild Leucadendron species which can exceed 10 feet.
- 🌱 These plants evolved in the nutrient-poor soils of the Cape Floral Region and are adapted to fire, thriving after burning—they contain special oils that help them recover quickly from disturbance.
