Swamp lily (Crinum americanum), also known as the seven sisters, string lily, or powder lily, is a native plant that could be the perfect addition to your Florida landscape. Find out if this low-maintenance, fragrant perennial is right for your garden or landscape: The 9 Principles of Florida-Friendly Landscaping™.
Origins of the Florida Swamp Lily
The swamp lily is native to the southeastern United States and is commonly found in moist, swampy areas, particularly in Florida’s wetlands, stream banks, and coastal regions. This evergreen perennial is appreciated for its striking, trumpet-shaped flowers and its resilience in Florida’s climate.
Growing Conditions and Characteristics
The swamp lily is an excellent choice for native plant gardens, wetland gardens, and naturalistic landscapes. This plant thrives in USDA Hardiness Zones 7 to 11. It can grow up to 4 feet tall and spread 2 to 3 feet wide, making it a wonderful option for small and large landscapes. Swamp lily can also be used along pond edges or water features for a pop of year-round, delicate white or pink-striped flowers.
Swamp lily prefers slightly acidic, well-drained, moist soils and requires partial shade environments. While this plant thrives in wet, swampy conditions but can also grow in slightly drier areas with regular moisture and can handle occasional periods of dryness. Once established, it is drought-tolerant, salt tolerant, and pest-resistant. This plant is a great option for gardens near water features, as well as areas that are prone to flooding.
The swamp lily produces flowers in spring, summer, and fall, and fruit follows the blooms. Its characteristic flowers bloom in clusters, with a fragrance that attracts pollinators, like bees and butterflies. Its long, narrow leaves grow in a rosette, a fan-like arrangement, from the base of the plant. In the winter, the plant continues to produces flowers and fruit.
Why Plant Native Species?
Native species, like the swamp lily, typically require less water and maintenance than non-native plants, making them more sustainable choices for landscaping. Additionally, native plants are better adapted to local soil and weather conditions that creates a healthier, resilient garden. By planting the swamp lily, gardeners support local wildlife and promote biodiversity.
