Cupressus cashmeriana - Bhutan Cypress, Kashmir Cypress - 10 seeds

Plant Description

Name: Cupressus cashmeriana
Common Names: Bhutan Cypress, Kashmir Cypress, Weeping Cypress

Cupressus cashmeriana, commonly known as the Bhutan Cypress or Kashmir Cypress, is an elegant coniferous tree native to the eastern Himalayas, particularly Bhutan and parts of India. This tree is highly valued for its distinctive, drooping branches that give it a graceful, weeping appearance. The foliage is a striking blue-green or silver-blue, and the branches cascade down in soft, feathery layers, making it a popular choice for ornamental landscaping in gardens and parks.

The Bhutan Cypress can grow to an impressive height of 20-25 meters (65-82 feet) in cultivation, but in its native habitat, it can reach up to 45 meters (148 feet) or more. It has a conical shape with a narrow crown and smooth, grey bark that peels in thin strips. The tree produces small, round cones that are 1.5 to 2.5 cm in diameter, with a purple-green hue when young that matures to a brownish color. Cupressus cashmeriana is highly regarded not only for its aesthetic qualities but also for its cultural and religious significance in Bhutan, where it is often planted near monasteries and temples.

Cultivation of Cupressus cashmeriana

Conditions:

1. Light: Cupressus cashmeriana thrives in full sun to partial shade. It requires at least 4-6 hours of sunlight per day for optimal growth. While it can tolerate some shade, full sun exposure helps maintain its dense foliage and vibrant color.
2. Temperature: This tree prefers cool, temperate climates and is best suited for USDA hardiness zones 8-10. It can tolerate a wide range of temperatures but prefers cooler conditions. It is sensitive to extreme heat and cold, particularly frost and snow loads, which can damage its delicate branches.
3. Soil: Bhutan Cypress grows best in well-drained, slightly acidic to neutral soils. It prefers loamy or sandy soil with good drainage but can adapt to a range of soil types, including clay, provided there is no waterlogging.
4. Water: Regular watering is essential, especially during the tree's early years. It prefers evenly moist soil but is somewhat drought-tolerant once established. Overwatering or poorly drained soil can lead to root rot.

Planting and Care:

1. Planting: Plant Cupressus cashmeriana in a location that provides adequate space for its mature size, away from buildings or other trees. Ensure the planting hole is twice the width of the root ball but not deeper than the root ball itself. Water thoroughly after planting to settle the soil around the roots.
2. Fertilization: Fertilize with a balanced, slow-release fertilizer in early spring to promote healthy growth. Use a formulation suitable for conifers, and avoid over-fertilization, which can lead to excessive growth and weaken the plant.
3. Pruning: Minimal pruning is required, primarily to remove any dead or damaged branches and to maintain the desired shape. Prune in late winter or early spring before new growth begins. Avoid heavy pruning, which can stress the tree and lead to sparse growth.

Propagation

1. Seeds: Cupressus cashmeriana can be propagated from seeds, which are collected from mature cones. Sow seeds in well-draining soil in a cool, shaded area. Germination may take several weeks to months and requires consistent moisture and cool temperatures.
2. Cuttings: Propagation from cuttings is also possible. Take semi-hardwood cuttings in late summer or early autumn and plant them in a well-draining mix. Provide a humid environment and bottom heat to encourage rooting, which can take several months.
