Lily Of The Nile

We cannot be positive without seeing your plants in flower but the foliage resembles the lily of the Nile. If it is, the large clusters of blue, purple, lavender, or white trumpet-shaped flowers on tall stems will arise from the lily of the Nile plant in spring. It is a common but beautiful landscape plant where conditions are naturally dry, and does well as long as the site is sunny and the soil well-drained. Leaves can get nipped by hard freezes and sunburned in heat waves. Plants prefer full sun to part shade, regular water and are pretty resilient to many growing conditions. Fertilize annually with a formula made for flowering perennial plants, but the plant will usually perform satisfactorily even without fertilizer.
