Peruvian lilies, also known as lilies of the Incas, are perennial tuberous plants that originate from South America. They resemble lilies but are not true lilies. These plants produce stunning flowers that can last up to three weeks as cut flowers in a vase. Peruvian lilies grow to be about 20 inches to just over 3 feet and typically spread through their roots. To thrive, they require rich, well-draining soil, full sun, and regular moisture of one inch of water per week. However, they will need shade from the afternoon sun in hot climates. While Peruvian lilies are mildly toxic to humans, they are non-toxic to cats, dogs, and horses. When caring for Peruvian lilies, plant them in the spring after all danger of frost has passed and soil temperatures have reached 60 degrees Fahrenheit. Handle their brittle tuberous roots with care when planting and ensure that they receive one inch of water per week to keep the soil moist.

Peruvian lilies thrive in full sun for six to eight hours, but in hot climates, they would prefer some shade during the peak of the afternoon sun. For best results, use fertile, well-drained soil with a slightly acidic pH (5.5-6.5), which can be achieved by adding organic amendments such as compost or leaf mold. These plants require regular moisture, especially during the summer season, so water them at least once a week or when the soil surface feels dry. To prevent the production of blind stems, plant the tubers in partial shade or an area that receives only morning sun if temperatures are in the upper 90s. In humid areas, provide adequate spacing to allow for air circulation, which will help carry away spores of fungal diseases like botrytis. Use a balanced flower fertilizer for one feeding in early spring, and then every two weeks for more productive results. Peruvian lilies are hybrids developed from Alstroemeria aurea and breeders have focused on introducing new colors for the cut flower market. Some popular varieties include ‘Fougere,’ ‘Moulin Rouge,’ ‘Mauve Majesty,’ ‘Indian Summer,’ and ‘Princess Eliane.’

To prevent Peruvian lilies from directing energy into seed production, cut them back after blooming. When the plants have spread too much, pulling up less productive stems will encourage younger plants from newly formed tubers to flourish. Peruvian lilies can be propagated by dividing their roots or growing from seed. The easiest and most reliable method is dividing the tuberous roots in early spring before new growth begins. Peruvian lilies can thrive in large containers paired with trailing plants that enjoy the same growing conditions. In colder climates, you can bring pots indoors for winter and store them as dormant plants in a cool, dry location. Common pests and diseases include slugs, mites, aphids, whiteflies, botrytis (gray mold), and various fungi that cause root rot. To encourage more blooms, deadhead spent flowers and provide bright sunlight, a balanced diet, and one inch of water per week. In a favorable garden location, Peruvian lilies will live almost indefinitely as the tuberous roots will gradually spread and colonize the area. When using Peruvian lilies in the landscape, it is best to plant them behind other species that disguise the base of the plants. When harvesting Peruvian lilies for cut arrangements, grasp the flower stem near ground level and pull laterally to detach the stem from the root crown.
