Calochortus bruneaunis, commonly known as the Green Stripe Mariposa Lily or Bruneau Mariposa Lily, is a charming perennial wildflower indigenous to the western United States, specifically found in Idaho, Nevada, and Oregon. This species is characterized by its slender stems that bear one to several showy, bowl-shaped flowers atop each, ranging in color from creamy white to light pink or lavender, often adorned with intricate purple markings and golden centers. The plant's grass-like foliage and elegant blooms make it a sought-after addition to native plant gardens. Typically thriving in well-draining, sandy soils within dry, open habitats like sagebrush plains or grasslands, the Bruneau Mariposa Lily tends to bloom from late spring into early summer, attracting pollinators such as bees and butterflies. Its delicate and alluring appearance, coupled with its resilience to arid conditions, contributes to its appeal among wildflower enthusiasts and gardeners seeking to incorporate native flora into their landscapes. Zones 5-7
Germination
To successfully germinate Calochortus bruneaunis seeds, start by mimicking their natural dormancy-breaking process. Provide a period of cold stratification by refrigerating them for a few weeks. Begin by preparing a well-draining planting medium composed of a mix of sand and peat or a commercial seed-starting mix. Sow the seeds on the surface of the soil mixture, pressing them lightly into the substrate. Moisten the soil gently without oversaturating it, and cover the container with a clear plastic lid or a plastic wrap to create a greenhouse-like environment. Place the container in a warm, brightly lit area, ensuring it receives indirect sunlight. Germination typically occurs within several weeks to a few months, and as the seedlings emerge, gradually expose them to more direct light and adjust watering to keep the soil consistently moist but not waterlogged. Once the seedlings have developed a few sets of leaves, they can be transplanted carefully into individual pots or an outdoor garden space with well-draining soil and adequate sunlight.
