Plants within the genus rush-lily thrive in well-draining soil, require full sun to partial shade, and need moderate watering. To plant, select an area with appropriate light, improve soil by adding organic matter if needed, and ensure good drainage. Space plants according to their mature size, plant at the same depth as the container, and water thoroughly after planting. Mulching helps retain moisture. It's essential to research individual species' needs within the genus rush-lily for optimum growth and bloom.
