The Elegant Sculptural Bloom
Calla lilies are among the most elegant and iconic flowers in floristry. With their sleek, sculptural form and striking colors, they are a favorite for weddings, luxury arrangements, and modern floral designs. Native to southern Africa, Calla lilies combine grace, minimalism, and versatility, making them ideal for both bold statements and delicate accents.
While widely cultivated in gardens and floral production, Calla lilies originate from wetland and marshy areas, adapting naturally to subtropical climates.
