California Bluebells or Desertbells are a breathtaking wildflower that features velvety cobalt-blue bell-shaped flowers 1-2 inches wide that are native to the deserts of California. This annual wildflower blooms from late winter to early spring and reaches a height of 6-12 inches, making it perfect for ground cover or borders. The plant thrives in full sun and are drought-tolerant once mature, making it ideal for xeriscaping or desert-themed gardens. The plant's natural habitat in the arid regions of California makes it highly drought-tolerant, allowing it to thrive in hot, dry conditions with minimal water. Their ability to thrive in a range of soil types and tolerate less-than-perfect conditions makes them ideal for both beginner and experienced gardeners. Desert Bluebells are known for its ability to attract pollinators, especially bees, due to its vivid blue flowers and rich nectar supply.

Planting Instructions:

Soil Preparation:

Choose an area with heavy, well-draining soil that receives at least 6 hours of sunlight each day. Remove weeds, large rocks, and litter from the planting area. Leave small weeds and dead grass, they will enrich the soil when turned under. Spade or till the soil 6-8 inches deep. Loosening the soil will help the plant establish strong roots. If the soil is heavy or clay-like, mix in some sand or compost to improve drainage. Optionally, form rows of soil beds 4-6 inches high and at least 12 inches apart. This formation of ridges will help with drainage, ensure good airflow, and make harvesting for cut flowers easier. Lay down 1/2"-3/4" peat moss, sawdust, or potting soil, the soil surface. This layer is beneficial for flower seeds because it can the improve the germination environment and prevent soil crusting.

Planting:

Starting indoors is not recommended because California Bluebells germinate best in 50F-55F temperatures. Plant after all danger of frost has passed in spring and soil temperatures reach at least 50F. To plant, make holes 1/16 inch deep and spaced 6-8 inches apart down the rows of raised beds. Plant 2-3 seeds per hole, then cover thinly with soil. In small plots, flower seeds may be scattered and gently watered in. Once seedlings emerge, plants can separated and spaced 6-8 inches apart to allow room for mature plants to spread and prevent overcrowding. Water after planting.

Within-Row Spacing:	6-8 inches
Between-Row Spacing:	12-18 inches

Care During the Season:

California Bluebells thrive with minimal care. Ensure plants receive full sun for most of the day to encourage robust growth and vibrant blooms. Water regularly to keep the soil evenly moist, but be mindful not to overwater, as California Bluebells prefer well-draining soil. During hot, dry spells, you may need to water more frequently, especially if the plant is in a container or a less-than-ideal soil mix. Deadhead spent flowers to promote continuous blooming and to prevent self-seeding if you don't want it to spread. If the plant starts to become leggy or overgrown, you can trim it back to maintain a tidy shape and encourage new growth. Adding a light application of balanced fertilizer early in the season can support healthy growth, especially in poor soil. Be sure to protect the plant from frost in cooler climates, as it is best suited for USDA zones 9-11 and may need to be overwintered indoors or treated as an annual in colder regions.
