Delphinium vs Quamash Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Delphinium
Delphinium spp.
Delphiniums are perennial herbaceous plants known for their tall, striking flower spikes. They typically grow outdoors and are prized for their vibrant blue, purple, pink, and white flowers. The plant has deeply lobed leaves and a robust stem that supports the flower spike. They are not suited for indoor growing due to their high light requirements and size. People grow them in gardens for their aesthetic appeal and to attract pollinators.
Quamash
Camassia quamash
Camassia quamash is a perennial herb with a bulbous base. It is primarily an outdoor plant, known for its striking blue to violet star-shaped flowers that bloom in spring. The plant grows from a bulb and features long, linear leaves. It is traditionally grown for its edible bulbs, which were a staple food for many Indigenous peoples of North America. While beautiful, it's challenging to replicate its natural growing conditions indoors, making it unsuitable as a houseplant.

❓ Frequently Asked Questions — Comparing These Plants
Delphinium
What are the light requirements for Delphinium?
Delphiniums are sun-loving plants and require at least six hours of direct sunlight daily to flourish. Insufficient light can lead to weak stems, poor flowering, and increased susceptibility to diseases. In hotter climates, some afternoon shade can be beneficial to prevent scorching. When selecting a location, consider the sun’s path and ensure the plants receive ample morning sun. Delphiniums grown in partial shade may still survive, but their blooms will be significantly diminished. If growing indoors, supplement with grow lights to provide the necessary intensity and duration of light. Rotate the plant regularly to ensure even light exposure.
How do I care for Delphinium?
Delphiniums require specific care to thrive. Plant in well-draining soil enriched with organic matter. Full sun (at least 6 hours daily) is crucial for optimal blooming. Water deeply but infrequently, allowing the soil to dry slightly between waterings. Fertilize regularly during the growing season with a balanced fertilizer, switching to a high-phosphorus fertilizer as buds develop to promote abundant blooms. Stake tall varieties to prevent them from collapsing under the weight of their flowers or in windy conditions. Deadhead spent blooms to encourage reblooming. Protect from slugs and snails, which can damage young plants. Provide adequate air circulation to prevent fungal diseases. Mulch around the base of the plant to retain moisture and suppress weeds.
How do I propagate Delphinium?
Delphiniums can be propagated through division, stem cuttings, and seeds. Division involves separating mature clumps in early spring or fall. Carefully dig up the plant and divide the root ball into sections, ensuring each section has healthy roots and shoots. Stem cuttings can be taken in spring. Select healthy, non-flowering stems and cut them into 4-6 inch sections. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a well-draining potting mix and keep them moist. Seeds can be sown indoors in late winter or early spring. Sow seeds thinly in a seed starting mix and keep them moist and warm. Germination typically takes 2-3 weeks.
Quamash
What are the light requirements for Quamash?
Quamash thrives in full sun to partial shade. Ideally, it should receive at least six hours of direct sunlight each day for optimal flower production. In hotter climates, some afternoon shade can prevent scorching of the foliage. When grown in partial shade, the plant may produce fewer flowers and the stems may be slightly weaker. Ensure that the planting location provides adequate sunlight during the spring growing season when the plant is actively developing. Insufficient sunlight can result in leggy growth and reduced flowering. The orientation of the planting site can also influence light exposure. South-facing locations typically receive the most sunlight, while north-facing locations receive the least. Adjust the planting location accordingly to provide the optimal light conditions for Quamash.
How do I care for Quamash?
Quamash thrives in full sun to partial shade, requiring at least 6 hours of sunlight daily for optimal blooming. Plant bulbs in well-drained soil that retains moisture. Water deeply and regularly during the growing season, especially during dry spells. Reduce watering after flowering as the plant enters dormancy. Fertilize in early spring with a balanced fertilizer to promote healthy growth and abundant blooms. Avoid over-fertilizing, which can lead to excessive foliage growth at the expense of flowers. Deadhead spent flowers to encourage bulb development. Provide adequate air circulation to prevent fungal diseases. Protect from excessive winter moisture in poorly draining soils to prevent bulb rot. Mulch around the plants to conserve moisture and suppress weeds. Divide clumps every few years to prevent overcrowding and maintain vigor. Monitor for pests and diseases, and treat promptly if necessary.
How do I propagate Quamash?
Quamash can be propagated by bulb division or seed. Division is the most common and easiest method. In late summer or early fall, after the foliage has died back, carefully dig up the clump of bulbs. Gently separate the individual bulbs, ensuring each has healthy roots attached. Replant the bulbs immediately in a well-prepared bed with well-draining soil. Space the bulbs approximately 6-8 inches apart. Water thoroughly after planting. To propagate by seed, collect seeds from dried flower heads in late summer or early fall. Sow the seeds in a cold frame or greenhouse in the fall. Germination can be slow and may take several months. Seedlings can be transplanted to the garden in the spring after they have developed several leaves.
