Alstroemeria flowers are similar to lilies, hence their common names of Peruvian lily or lily of the Incas. However, the Peruvian lily has noticeably more fragile petals than true lilies do. Alstroemeria blooms are brightly colored with pleasing stripes and spots and the stems of the lily of the Incas are thin. Alstroemeria flowers are a prime selection for when a design calls for a buoyant and flirty version of the usual lily. The Peruvian lily communicates ideas of wealth, prosperity, and fortune.
