Lilium philadelphicum, commonly known as the Wood Lily or Prairie Lily, is a bulbous geophyte native to North America. It is part of the Liliaceae family and the genus Lilium. This plant is known for its striking orange-red flowers and typically blooms in the summer. It prefers temperate climates and goes through a dormancy period during the winter months.
Lilium philadelphicum requires bright, direct sunlight for optimal growth. It thrives in moderate temperatures and prefers moderate humidity levels. Water the plant when the soil partially dries out, ensuring it does not become waterlogged. This plant is best suited for outdoor growth in temperate climates.
Soil
The Wood Lily prefers well-draining loam soil. It is important to ensure the soil has good drainage to prevent bulb rot. A slightly acidic to neutral pH is ideal for this plant.
Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant during the growing season, typically in the spring and early summer, to support healthy growth and flowering.
Repotting
Repotting is generally not necessary for Lilium philadelphicum as it is typically grown outdoors. However, if grown in containers, repot the bulbs every few years to refresh the soil and provide more space for growth.
Propagation
Lilium philadelphicum can be propagated by dividing the bulbs. The best time to propagate is during the dormancy period in late fall or early spring. Carefully separate the bulbs and replant them in well-draining soil.
Pruning
Pruning is not required for this plant. However, you can remove spent flowers to encourage more blooms and maintain the plant's appearance.
Toxicity
Lilium philadelphicum is toxic to pets, particularly cats. Ingestion can cause severe kidney damage and other health issues. It is advisable to keep this plant out of reach of pets and children.
Additional
Ensure the plant is protected from strong winds, as the tall stems can be prone to damage. Mulching around the base can help retain soil moisture and protect the bulbs during the winter months.
