How to grow Camassias organically

Growing Camassias organically is a wonderful way to add striking blooms and a touch of wild beauty to your garden. Known for their star-shaped flowers and tall, elegant stalks, Camassias are relatively easy to grow and maintain without the use of synthetic chemicals. Here’s a guide on how to cultivate these charming bulbs organically.


Camassias, commonly known as quamash or wild hyacinths, thrive in a range of environments and are particularly suited to organic cultivation. They’re native to North America and were historically valued as a food source by Indigenous peoples. Their resilience and low maintenance requirements make them ideal for organic gardens.

Choosing Your Bulbs

Select high-quality, organic Camassia bulbs from reputable nurseries or garden centers. Look for bulbs that are firm and free of mold or damage. Opt for species like Camassia leichtlinii or Camassia quamash, depending on your climate and soil type.

Site Preparation

Camassias prefer full sun to partial shade and well-draining soil. They are tolerant of moist conditions, making them excellent for areas of your garden that are not excessively dry.

  1. Soil Testing: Test your soil to determine its type and pH. Camassias perform best in slightly acidic to neutral soil (pH 6-7).
  2. Amending Soil: If your soil is heavy clay or sandy, enrich it with plenty of organic matter such as compost or well-rotted manure to improve drainage and nutrient content.


The best time to plant Camassia bulbs is in the fall, a few weeks before the ground freezes. This allows them to establish roots before the winter.

  1. Planting Depth and Spacing: Plant bulbs approximately 4 to 6 inches deep and 4 to 8 inches apart. Point the tip of the bulb upward.
  2. Watering After Planting: Water your newly planted bulbs well to settle the soil around them.


Camassias are low-maintenance, but a few key practices will help them thrive:

  1. Watering: Keep the soil moist but not waterlogged during the growing season. Once established, Camassias are relatively drought-tolerant.
  2. Mulching: Apply a layer of organic mulch around the plants to help retain moisture, suppress weeds, and provide nutrients as it decomposes.
  3. Fertilizing: Feed your Camassias with a balanced organic fertilizer in early spring as shoots appear.

Pest and Disease Management

Camassias are generally resistant to pests and diseases. However, practicing good garden hygiene such as removing dead foliage and avoiding overhead watering can prevent fungal diseases.

Blooming and Aftercare

Camassias bloom in late spring to early summer, offering spikes of blue, white, or purple flowers.

  1. Deadheading: While not necessary, removing spent flowers can tidy up plants after blooming.
  2. Post-Bloom Care: Allow the foliage to die back naturally. This process helps the bulbs store energy for the next growing season.
  3. Division: Divide clumps every few years in late summer if growth seems crowded or blooms diminish.


Organically growing Camassias is a rewarding endeavor that enhances your garden with minimal effort. Their tall, graceful spikes of starry flowers not only attract pollinators but also add a burst of late spring to early summer color. By following these simple steps, you can enjoy the natural beauty of Camassias for years to come.
