Origin
Zigadenus micranthus Eastw. var. fontanus (Eastw.) O.S. Walsh ex McNeal, commonly known as small-flowered camas or death camas, is a perennial herbaceous plant in the Melanthiaceae family native to North America. It is found in various habitats, including meadows, low-elevation mountains, and along streams or rivers. It is known to grow in regions such as California, Oregon, Montana, Idaho, and Washington.
Common Names
Small-flowered camas is known by several common names, including death camas, small camas, little camas, Sagebrush camas, and fontanus camas. These names are due to the plant's poisonous nature, with all parts of the plant containing toxic alkaloids, which can be fatal when ingested in large quantities.
Uses
Despite being poisonous, small-flowered camas has been used by Native American tribes for various medicinal purposes. The roots of the plant were boiled and used as a poultice for treating bruises and wounds. Additionally, the roots were eaten after being heated and cooled repeatedly to remove the toxins, similar to the preparation of the edible camas bulb. However, the ingestion of any part of this plant is not recommended due to its toxicity.
General Appearance
The plant grows to an average height of 30-70cm and has narrow linear basal leaves, which are less than 3mm wide. The stem bears tiny white to greenish-yellow flowers with three petals that bloom from May to July. The flowers grow in clusters at the top of the stem and are typically up to 6mm in size. The plant produces a bulb, which is usually ovoid, oblate, or elongated. The bulb of small-flowered camas can be distinguished from other camas varieties by its small size and lack of tunic or mesh covering.
Overall, while small-flowered camas' appearance may be deceiving, it remains an important part of North American flora.Growth Conditions for Zigadenus micranthus Eastw. var. fontanus (Eastw.) O.S. Walsh ex McNeal

The pH should be neutral to slightly acidic or slightly alkaline. Avoid planting it in heavy soils that retain moisture, as it can lead to root rot and other diseases.
Adding compost or organic matter to the soil can help improve the texture of the soil and increase its water retention capacity. Regular watering is also important to keep the soil moist but not waterlogged.
With proper care and adequate growing conditions, Zigadenus micranthus Eastw. var. fontanus (Eastw.) O.S. Walsh ex McNeal can produce beautiful white flowers in summer, and its foliage can remain attractive throughout the growing season.
Cultivation methods
Zigadenus micranthus Eastw. var. fontanus (Eastw.) O.S. Walsh ex McNeal is a perennial herb that is native to the Rocky Mountains. It grows well in full sun to partial shade and well-draining soil. The plant prefers a dry to a slightly moist environment and can tolerate drought once established.
It is advisable to plant Zigadenus micranthus Eastw. var. fontanus in the spring or early fall. Sow the seeds just below the soil surface in well-draining soil. The plant will germinate within one to three weeks.
Once the plant matures, it can be propagated by dividing the rhizomes. This should be done in the spring or early fall before the onset of new growth.
Watering needs
Zigadenus micranthus Eastw. var. fontanus does not require much watering, and overwatering can cause root rot. The plant prefers a dry to a slightly moist environment and can tolerate drought once established. It is advisable to water the plant when the top inch of soil is dry. When watering, make sure to saturate the soil fully and allow the excess water to drain.
Fertilization
Zigadenus micranthus Eastw. var. fontanus does not require much fertilization, and overfertilization can harm the plant. The best time to fertilize the plant is in the spring before the onset of new growth. Use a balanced plant fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Follow the instructions on the fertilizer package.
Pruning
Zigadenus micranthus Eastw. var. fontanus does not require much pruning unless it becomes overgrown or damaged. The best time to prune the plant is in the fall after the plant has finished flowering. Cut back the stem to just above the ground level. If pruning to control growth, it is best to cut back only a portion of the plant to ensure that it continues to thrive.
Propagation of Zigadenus micranthus Eastw. var. fontanus (Eastw.) O.S. Walsh ex McNeal
Zigadenus micranthus Eastw. var. fontanus (Eastw.) O.S. Walsh ex McNeal, commonly known as sandhill death camas, is a native plant species to North America. It belongs to the family Melanthiaceae and is an herbaceous perennial plant that grows up to 60 cm tall. The plant produces small, white flowers that bloom in the summer and has long, narrow leaves that are mostly basal.
Propagation methods
Propagation of Zigadenus micranthus Eastw. var. fontanus can be done through seed, division, and bulb offsets.
Seed propagation
Seeds from sandhill death camas should be sown in late summer or early fall. To improve germination, the seeds can be stratified for several weeks in cold, moist conditions before planting. Plant the seeds in well-draining soil, and keep the soil consistently moist until the seeds germinate. Once the plants are established, they can be transplanted into their permanent position.
Division propagation
Zigadenus micranthus Eastw. var. fontanus can also be propagated through division. The plants should be divided in early spring before the growing season starts. The plant should be lifted carefully from the soil, and the roots should be separated gently. Each division should have several shoots and a good root system. The divisions can be replanted immediately in well-draining soil and watered thoroughly.
Bulb offsets propagation
The plant produces small bulb offsets that can be removed and replanted in a separate location. The offsets should be removed in the fall after the plant has finished blooming. Carefully dig around the bulb and remove the offsets. Replant the offsets immediately in well-draining soil and water thoroughly to ensure they establish properly.
Propagation of Zigadenus micranthus Eastw. var. fontanus should be done with care, as the plant contains toxic alkaloids that can cause serious health problems if ingested. Therefore, it is crucial to always wear gloves when handling this plant, and to keep it away from children and pets.
