Camassia: Care, Types, Propagation, and Troubleshooting
Camassia Care
Camassia plants are relatively easy to care for, thriving in full sun or partial shade with moist, well-drained soil. Regular watering is essential, especially for plants in full sun. Avoid overwatering, as soggy conditions can lead to problems. Fertilization is generally not necessary, but adding compost to the soil can provide a boost of nutrients.
Types of Camassia
There are several species of camassia, each with its own unique characteristics:
- Camassia leichtlinii: Known as large or great camas, this species grows up to 48 inches tall and produces blue, purple, or white blooms.
- Camassia quamash: Also known as common camas, this variety is more petite, reaching a mature height of about 18 inches. It’s known for its deep blue flowers.
- Camassia scilloides: Sometimes called Atlantic camas, this species is the only camassia native to eastern North America and produces white or light blue flowers.
Propagation
Camassia plants multiply by means of bulb offsets, making propagation relatively easy through division. In the fall, gently dig up the plant and separate the offsets from the main bulb. Plant the offsets in well-drained soil, about 6 inches deep and 6 inches apart. Water thoroughly after planting.
Bloom
Camassia typically blooms in late spring or early summer, producing star-shaped flowers in shades of blue, purple, or white. The flower stalk can support up to 100 blooms, with the bottom buds opening first and the topmost buds opening later. The total bloom period lasts about six weeks.
Encouraging More Blooms
If your camassia plant is producing more foliage and fewer flowers, it may be a sign of overcrowding. Divide the plant in the fall to reduce crowding and promote more flower production. Another factor that can affect blooming is moisture imbalance. Ensure that the soil is consistently moist but not overly saturated.
Common Problems
Camassia plants are generally hardy and resistant to pests and diseases. However, they can occasionally experience the following problems:
Wilting Leaves or Stems: Overwatering can cause the leaves or stems of camassia plants to wilt or droop. Reduce the frequency of watering or amend the soil to improve drainage.
Yellowing Leaves: After flowering, camassia plants naturally shed their leaves as they prepare for dormancy. Allow the leaves to turn yellow before removing them.
FAQ
Where is the best place to plant camassia?
Camassia prefers a sunny spot with well-drained soil and is often planted along garden borders or to attract pollinators.
Do camassia bulbs spread?
Camassia bulbs do multiply, forming larger clumps over time. However, they do not spread aggressively through the garden.
Is camassia deer-resistant?
Yes, camassia plants are typically deer-resistant, making them a good choice for areas with wildlife.
