| Design Ideas | The flowers of Fortnight Lily glow in the dark and look exotic in tropical gardens--despite the plant's tolerance of a hard frost. It is one of the best all-purpose plants for beds and borders, where it functions a lot like an Iris, but with a much longer bloom period. This plant is equally at home in Asian-garden schemes, where it is grown beside koy ponds or streambeds as a flowering reed. With its drought-resistance, it is commonly used in dryland gardens throughout the Southwest, where it takes inland heat in stride. Grow as a low hedge, partition, or simply plant in big pots on a balcony or porch. |
