Calotropis Gigantea
Often called the Crown Flower or Giant Milkweed, this architectural shrub is a staple of tropical landscapes and royal history. Its most striking feature is its waxy, star-shaped flowers that resemble a tiny royal crown, a detail that made it a favorite of Hawaiian Queen Liliʻuokalani. While it looks like a tough, desert-hardy plant, it plays a delicate and vital role in the lifecycle of the Monarch butterfly.
In Hawaii, the Crown Flower is the traditional choice for making lei. Because the flowers are so durable and "waxy," a Crown Flower lei can last for days without wilting, symbolizing enduring affection and royalty.
