Overview
Delphinium parryi Gray var. montanum Munz is a flowering plant native to North America. It is a subspecies of Delphinium parryi and is commonly known as mountain larkspur or Parry's larkspur.
Appearance
Mountain larkspur is a tall perennial plant that can grow up to 3-4 feet in height. It has a straight stem that is covered in small hairs and is topped with a cluster of blue to purple flowers. The flowers have a distinctive shape, with a spur that extends behind the petals. The leaves of the plant are deeply divided and have a bluish-green color.
Uses
Mountain larkspur has been traditionally used for medicinal purposes by some Native American tribes, as the plant contains alkaloids that have pain-relieving and anti-inflammatory properties. However, the plant is also highly toxic and can cause serious illness or even death if ingested. It is best to avoid using the plant for medicinal purposes without proper training and guidance.
As a garden plant, mountain larkspur is highly prized for its tall and impressive appearance. It is often used in cottage gardens or mixed borders, and can also be used as a cut flower for floral arrangements.

Propagation of Delphinium parryi Gray var. montanum Munz
Delphinium parryi Gray var. montanum Munz, commonly known as mountain larkspur, is a wildflower plant native to the western United States. This plant can be propagated through various methods, including seed propagation, stem cutting, and division of roots.
Seed Propagation
Seed propagation is the most common method used to propagate Delphinium parryi Gray var. montanum Munz. It is also the easiest and most reliable method. The seeds for this plant can be collected from the pods that develop after the flowering season. The collected seeds should be cleaned and stored in a cool, dry place until planting time.
For seed propagation, sow the seeds in a well-draining potting mix in the fall or spring. The seeds should be planted about 1/4 inch deep in the soil. Water the soil gently so that the seeds don't get dislodged. Keep the soil moist and ensure that the container gets indirect sunlight.
After about two weeks, the seeds will germinate, and the seedlings will start to grow. Once the seedlings have grown four to six leaves, they can be transplanted into their permanent location.
Stem Cutting Propagation
Propagation of Delphinium parryi Gray var. montanum Munz through stem cuttings is ideal for those who want a quick start to their garden. The best time to take stem cuttings is during early summer when the plant is in its growing phase.
To propagate the plant with stem cutting, select branches with strong stems that are about four to five inches long and cut them with a sharp, sterile blade. Remove the lower leaves from the stem, leaving only one or two leaves on the top. Dip the cut end of the stem in rooting hormone powder and then plant it in a well-draining soil mix. Keep the soil moist and cover the pot with plastic to create a humid environment for the stem cuttings.
Division of Roots
Division of roots is another propagation method used for Delphinium parryi Gray var. montanum Munz. It is usually done during the fall or early spring when the plant is dormant. Dig up the plant carefully and separate the roots into clumps. Make sure that each clump has at least one healthy shoot and root system.
Plant the clumps in well-draining soil mix, keeping the plants at the same depth as before. Water the plant thoroughly after planting and keep the soil consistently moist until the plant has established its roots.
Propagation of Delphinium parryi Gray var. montanum Munz is simple and easy if you follow the right procedures and methods. You can get started with these methods and enjoy a full bloom of the mountain larkspur plant.
