common camassia


Camassia quamash, commonly known as common camas, is a perennial plant that is recognized for its striking star-shaped flowers. The flowers are typically a deep blue or purple color, though they can occasionally be found in lighter shades of blue to almost white. These blossoms form in a raceme, which is a cluster where the individual flowers are attached by short stalks along a central stem. Each flower has six petals that spread outward, creating an open, star-like shape. The leaves of the common camas are basal, meaning they grow from the base of the stem. They are long and sword-shaped with a slightly wavy margin and a glossy green appearance. They ascend directly from the ground and can often form a dense, grassy clump. The plant emerges from a bulb, which historically has been an important food source for various indigenous peoples of North America. The plant typically flowers in the late spring to early summer. Once flowering is finished, the plant will produce capsule-like fruit that splits open when mature, releasing small black seeds. The common camas grows naturally in meadows, prairies, and along stream banks, preferring moist environments with well-drained soil. The visual charm of the common camas lies not only in its alluring flowers but also in its orderly, vertical growth habit and the lush, verdant backdrop provided by its foliage, which showcases the floral display prominently. This combination of features makes the common camas a popular choice for naturalizing in gardens and for adding a splash of color to wildflower meadows.

  • skullToxicity

    • To humans

      Camas, specifically Camassia quamash, is generally not toxic to humans if properly prepared; in fact, it has been historically used as a food source by various Native American tribes. However, it's important to note that the bulbs must be cooked properly to break down naturally occurring inulin into fructose, which makes it edible. If camas bulbs are eaten raw or undercooked, they can cause gastrointestinal discomfort due to their high inulin content. Ensuring the bulbs are thoroughly cooked can prevent this issue. Moreover, it is crucial to correctly identify camas as it can be easily confused with the toxic death camas (Zigadenus species), which can lead to serious poisoning characterized by nausea, vomiting, abdominal pain, and possibly more severe symptoms such as hypotension or bradycardia if consumed.

    • To pets

      Camas is not widely known for being toxic to pets, but as with humans, the primary concern is the potential confusion with the toxic death camas, which can be very harmful to animals. If a pet were to ingest parts of the genuine Camassia quamash, especially in large quantities, it could experience mild gastrointestinal upset due to the inulin content. Conversely, if a pet ingests death camas, thinking it is Camassia quamash, it could suffer more severe symptoms including salivation, vomiting, hypotension, seizures, or even death without prompt veterinary treatment. It's important therefore to prevent pets from ingesting unknown wild plants and to seek veterinary attention if poisoning is suspected.

  • water dropWater

    The common camas or Camassia quamash should be watered moderately, ensuring the soil is kept moist but not waterlogged. Typically, during the spring and summer growing seasons, water every week with approximately 1 gallon for outdoor plants, depending on the weather conditions. Less frequent watering is necessary during the dormant season; every two to three weeks should suffice, provided the soil does not completely dry out. Always adjust watering based on rainfall, as too much water can lead to bulb rot.

  • sunLight

    The common camas prefers full sun to partial shade. It thrives best when it receives at least six hours of direct sunlight each day, though it can tolerate some light shade, especially in hotter regions. The ideal spot would allow for morning sunlight and some afternoon shade, aiding in the protection from the intense heat of the day.

  • thermometerTemperature

    The common camas is hardy and can withstand a temperature range from just above freezing, around 35 degrees Fahrenheit, to about 90 degrees Fahrenheit. The ideal growing temperatures are between 50 and 75 degrees Fahrenheit. Avoid exposing the plants to temperatures below the freezing point for prolonged periods to prevent damage to the bulbs.

  • scissorsPruning

    Pruning of common camas is not typically necessary for the health of the plant, but spent flower stalks can be removed after blooming to maintain a tidy appearance. Pruning should be done after the flowers have faded and leaves have begun to yellow, usually in late spring or early summer. This helps to redirect energy to the bulb for next year's growth.

  • circleLife cycle

    The life of Camassia quamash, commonly known as common camas, begins with seed dispersal, typically by wind and water. Germination occurs in moist soil conditions, often in early spring, after which the seedlings emerge and develop a bulb over time. The plant grows leaves that photosynthesize to provide energy for growth and further development of the bulb. Common camas enters a blooming phase in late spring to early summer, showcasing a spike of starry blue to violet flowers, which are pollinated by insects. After pollination, the flowers develop into capsules containing seeds, completing the reproductive cycle. The plant then enters a period of dormancy in the late summer or fall, where the foliage dies back, and the bulb survives underground until the next growth cycle begins.

    • Propogation time

      Spring to Summer

    • Propogation: Camassia quamash, commonly known as small camas, is usually propagated by dividing bulbs. The ideal time to propagate by division is in the fall when the plant has died back, and the bulb is dormant. To propagate small camas bulbs, carefully dig up the clump of bulbs and gently separate them. Each bulb should have a portion of the basal plate to ensure they can grow into a new plant. Replant the bulbs immediately at a depth of 2-4 inches (5-10cm) with the pointed end facing upward, spacing them about 4-8 inches (10-20cm) apart to give them room to grow. Ensure the area has good drainage and that the bulbs receive adequate water during their growth period in the spring.
