Rubrum lilies prefer to be planted in a location that receives full to partial sun exposure and well-draining soil that is rich in organic matter. They also require adequate moisture, so it is important to ensure the soil does not dry out completely. Rubrum lilies can be planted in garden beds, borders, or containers, but they thrive best in areas with good air circulation and protection from strong winds.
When planting, make sure to space them at least 12 inches apart and plant them at a depth of approximately 6 inches. Overall, the best place to plant Rubrum lilies is in a sunny, well-drained location with plenty of moisture and good air circulation.
