Dunn's mariposa lily (Calochortus dunnii)
Also known as: Dunn's Mariposa Lily
Dunn's mariposa lily (Calochortus dunnii) is a perennial herb that often blends into its surroundings until it flowers. Emerging from distinctive bulbous roots, it produces slender, grass-like leaves and tall, delicate stems. Each stem typically showcases a single, elegant, cup-shaped flower, predominantly in hues of white or pink with striking red or purple markings at the base of the petals.
This lily thrives in rocky, well-drained soils, commonly found on slopes in chaparral or coastal sage scrub habitats. Its drought resilience is notable, with its lifecycle finely attuned to the seasonal rainfall patterns of Southern California's Peninsular Ranges. The bulbous root system allows it to endure dry summers, making it a remarkable fixture in its native arid environments.

What Is the Ideal Temperature Range for Dunn's mariposa lily?
The ideal temperature range for Calochortus dunnii is between 60°F and 75°F. In this range, the plant experiences optimal growth conditions enabling it to thrive and bloom efficiently. Such temperatures provide the right balance of warmth and light, encouraging photosynthesis and nutrient uptake.
What Soil is Best for Dunn's mariposa lily?
Calochortus dunnii thrives in well-drained soil to prevent waterlogging, which is crucial for its bulb health. Ensuring good drainage helps avoid root rot and promotes healthy growth. This species prefers soil with moderate fertility, which supports its growth without overwhelming it with nutrients. Balanced soil fertility encourages steady flowering and robust leaf development. Maintaining a soil pH between 6.5 and 7.5 is optimal for Calochortus dunnii as it facilitates nutrient availability and absorption, crucial for vibrant blooms and sturdy foliage.
How to Fertilize Dunn's mariposa lily?
For Calochortus dunnii, a balanced fertilizer diluted to half strength is ideal. Use a 10-10-10 liquid fertilizer, applying it at a rate of 1 tablespoon per gallon of water. When applying slow-release fertilizer, follow the manufacturer's instructions, typically spreading 1 to 2 tablespoons per square foot around the base of the plant. Always be cautious not to exceed the recommended dosage to prevent nutrient burn.
How to Prune Dunn's mariposa lily?
Begin pruning Calochortus dunnii in either spring or summer, when the plant is actively growing. Focus on cutting back dead or diseased stems to encourage new growth. Use sharp, clean scissors or pruning shears for precise cuts. Aim to maintain a natural shape, trimming just above a leaf node or bud to stimulate healthy development.

How to Propagate Dunn's mariposa lily plant?
1
Fill seed trays with the chosen soil mix, ensuring it is moist but not waterlogged. Gently press the soil down to eliminate air pockets and ensure level planting beds.
2
Scatter Calochortus dunnii seeds evenly across the soil surface, keeping a sufficient distance between each to accommodate growth. Lightly cover with a thin layer of soil to protect from disturbance.
3
Place trays in a warm, bright location away from direct sunlight. Maintain consistent moisture by misting, avoiding overly wet conditions that can lead to rot.
How to Repot Dunn's mariposa lily plant?
1
Calochortus dunnii signals its need for repotting when its roots outgrow the current container, often visible at the drainage holes, or when the growth rate noticeably declines even under optimal conditions. Opt for repotting in spring or autumn when the plant undergoes active growth, minimizing stress.
2
Select a pot that is 2-3 inches wider in diameter than the current one. Ensure it has adequate drainage holes to prevent waterlogging. A slightly larger pot will give room for root expansion, promoting healthy growth and reducing the risk of root rot.
3
Opt for well-draining sandy soil, as Calochortus dunnii thrives in environments that prevent water accumulation. This type of soil ensures adequate aeration, reducing the risk of fungal diseases and enabling the roots to breathe and expand healthily.
