Camassia

The best time to plant Camassia bulbs is in the fall, typically from September through November, before the ground freezes. Planting during this period allows the bulbs to develop a strong root system before winter sets in. Camassias require a period of cold dormancy to trigger healthy spring growth and flowering. Choose a sunny or partially shaded location with well-drained, moisture-retentive soil. Plant the bulbs at a depth of about 4 to 6 inches and space them around 6 inches apart. Fall planting gives Camassia bulbs the best chance to thrive, ensuring a striking display of blue or white star-shaped flowers in late spring.

Yes, Camassia bulbs are perennial, meaning they come back year after year when grown in the right conditions. Once established, they are known to naturalize well, slowly spreading and creating larger clumps over time. Camassias thrive in moist, fertile soils and are ideal for wildflower meadows, damp borders, or areas near ponds. They are hardy in USDA zones 4–8 and can survive harsh winters without lifting. Minimal maintenance is required—just allow the foliage to die back naturally after flowering to help replenish the bulbs' energy for the next growing season. With proper care, Camassia bulbs will reward you with reliable spring blooms for many years.

Camassia bulbs should be planted at a depth of about 4 to 6 inches (10 to 15 cm) deep in the soil, with the pointed end facing upward. Proper planting depth is essential to ensure the bulbs develop strong roots and produce healthy, upright flower stalks in the spring. The spacing between bulbs should be approximately 6 inches (15 cm) apart to give them enough room to grow and multiply. Be sure to choose a location with well-draining soil and consistent moisture, especially during the growing season. Planting at the correct depth helps protect the bulbs from temperature extremes and promotes robust, long-lasting flowering.

Camassia bulbs perform best in full sun to partial shade, making them versatile for many garden settings. While they thrive in full sunlight, they are also well-suited to dappled or light shade, especially in woodland gardens or beneath deciduous trees that allow spring sun before leaf-out. Camassia prefers moist, fertile soil and will tolerate seasonal wetness, making it a great choice for borders, meadows, or areas near water features. In regions with hot summers, some afternoon shade can actually help prolong bloom time and keep the foliage looking fresh. Providing the right balance of sun and moisture ensures healthy growth and vibrant spring flowers.
