Some tribes used the plant to treat a wide range of ailments, such as skin irritations, snake bites, stomach aches, and headaches. The plant contains various alkaloids and has been known to cause toxicity in grazing animals such as sheep.
In contemporary times, Delphinium gypsophilum Ewan ssp. gypsophilum is primarily grown as an ornamental plant in gardens and landscapes. Its tall, eye-catching spikes of blue-purple flowers make it a popular addition to flower beds, borders, and cut flower arrangements.
Light Requirements
The Delphinium gypsophilum Ewan ssp. gypsophilum plant requires full sun to grow properly. It needs at least six hours of sunlight daily to produce beautiful blooms.
Temperature Requirements
The Delphinium gypsophilum Ewan ssp. gypsophilum plant prefers cooler temperatures and grows best in areas with moist and mild climate. It can withstand temperatures as low as -34°C (-30°F) and as high as 29°C (85°F). However, it grows best in areas with temperatures between 16°C to 21°C (60°F to 70°F).
Soil Requirements
The Delphinium gypsophilum Ewan ssp. gypsophilum plant grows well in rich, loamy soil that is well-draining. The soil pH should be between 6.5 to 7.5. It is advisable to mix some organic matter such as compost or peat moss into the soil before planting to improve nutrient levels and water retention capacity.
Cultivation
Delphinium gypsophilum Ewan ssp. gypsophilum is a perennial plant that prefers well-draining soil and full sunlight to partial shade. It can grow in USDA hardiness zones 4 to 8 and is often grown from seed or transplanted as young plants.
When planting from seed, it is best to sow them directly into the ground in early spring or late fall. The seedlings will emerge in two to three weeks and can be thinned to 12 to 18 inches apart once they reach two to three inches tall.
If transplanting young plants, it is best to wait until the last frost in your area has passed before planting them. Dig a hole twice the width of the plants' roots, making sure to keep the crown at soil level. Space plants 12 to 18 inches apart.
Watering Needs
Delphinium gypsophilum Ewan ssp. gypsophilum requires moderate to consistent moisture. The soil should be kept evenly moist but not waterlogged or saturated. During the growing season, the plant should receive at least one inch of water per week, either through rainfall or irrigation. Mulching around the base of the plant can help retain moisture and regulate soil temperature.
Fertilization
Delphinium gypsophilum Ewan ssp. gypsophilum benefits from an application of balanced fertilizer in early spring and again in midsummer. Use a slow-release granular fertilizer or liquid fertilizer with a balanced NPK ratio, following the package instructions for application rates. Avoid over-fertilization, as this can lead to leggy growth and decreased flowering.
Pruning
Deadheading spent blooms and cutting back the plant in midsummer after the first flush of flowers can encourage a second bloom in the fall. Cut the stems back to a set of healthy leaves just above the base of the plant. In the fall, cut back the entire plant to approximately two inches tall to prevent overwintering debris and promote healthy regrowth in the spring. Avoid pruning after the first frost, as this can damage the plant's tender new growth.
Propagation of Delphinium gypsophilum Ewan ssp. gypsophilum
Delphinium gypsophilum Ewan ssp. gypsophilum, commonly known as Gypsum larkspur possesses beautiful blue flowers and is an interesting addition to any garden. The plant can be propagated through three methods, including seed, cutting or division.
Propagation through Seeds
The easiest and most common way to propagate Delphinium gypsophilum is from seed. The seeds should be collected from the plant's pods in late autumn. Once the seeds are collected, they should be cleaned and stored in a cool and dry place until spring. In March or April, the seeds should be sown in trays of compost and placed in a warm and light place, such as a greenhouse or windowsill. The seedlings can be transplanted to their final position in May or June, once they have grown a few true leaves.
Propagation through Cuttings
Propagation through cuttings can be more challenging than seed sowing. The best time to take cuttings is in early summer, when the plant is in full growth. Cuttings of approximately 10cm length should be taken from the plant, just below a leaf node. The lower leaves can then be removed, and the cuttings should be inserted into a moist potting compost. The compost should be well-draining and placed in a bright and warm spot, with regular watering. After a few weeks, the cuttings should start developing roots, and once the roots are well established, they can be potted on into individual pots.
Propagation through Division
Propagation through division is another method that can help produce more plants from an existing one. This method should be carried out during the early part of the new growing season. To do so, the plant should be carefully dug up, and the root ball divided into several pieces, each with a shoot or a bud. Each division can then be replanted in individual pots or to their final place in the garden. Dividing the plant can encourage new growth and reduce the risk of disease.
Disease and Pest Management for Delphinium gypsophilum Ewan ssp. gypsophilum
Delphinium gypsophilum Ewan ssp. gypsophilum is a beautiful wildflower that blooms in mid-summer. It is a member of the buttercup family and is native to the western United States. As with any plant, Delphinium gypsophilum Ewan ssp. gypsophilum is susceptible to various diseases and pests that can damage or kill the plant.

Common Diseases
One of the most common diseases that can affect Delphinium gypsophilum Ewan ssp. gypsophilum is powdery mildew. This fungal disease produces a powdery white substance on the leaves and stems of the plant. To manage powdery mildew, remove and destroy any infected plant material and ensure proper spacing between plants for adequate air circulation. Additionally, you can apply fungicides that contain sulfur or potassium bicarbonate to prevent the spread of powdery mildew.
Another disease that can affect Delphinium gypsophilum Ewan ssp. gypsophilum is crown rot. This disease is caused by a fungus and can be identified by the rotting of the plant's crown. To manage crown rot, remove and destroy any infected plant material, improve soil drainage, and avoid overwatering the plant.
Common Pests
One of the most common pests that can affect Delphinium gypsophilum Ewan ssp. gypsophilum is aphids. These small, soft-bodied insects suck the sap from the plant's leaves and stems, causing the plant to weaken and potentially die. To manage aphids, wash them off with a strong blast of water or use insecticidal soap or neem oil to kill them.
Another common pest that can affect Delphinium gypsophilum Ewan ssp. gypsophilum is slugs. These slimy pests can eat holes in the plant's leaves and cause significant damage. To manage slugs, use slug baits or traps or handpick them off the plant.
Overall, managing diseases and pests is essential to the health and survival of your Delphinium gypsophilum Ewan ssp. gypsophilum. By taking preventive measures and employing the appropriate management techniques, you can protect your plant and enjoy its beauty for years to come.
