Port Orford Cedar Chamaecyparis lawsoniana 'Imbricata Pendula'
ABOUT
The Chamaecyparis lawsoniana 'Imbricata Pendula', commonly known as the Weeping Lawson Cypress, is a visually striking conifer with a unique growth habit. This plant is characterized by its elegant, pendulous branches that drape downward, creating a curtain-like effect. The foliage is dense with a fine, feathery texture, composed of small scales that overlap each other tightly. It displays a lush green to bluish-green color, which can appear silvery from a distance due to the way the light catches the leaves. During the growing season, the Weeping Lawson Cypress may develop small cones that add to its ornamental value. The cones are usually inconspicuous, blending in with the foliage. This plant's dramatic weeping form and dense, graceful boughs make it a focal point in any landscape design where its unique silhouette can be showcased. Despite its distinctive appearance, the Weeping Lawson Cypress maintains an air of softness and delicacy due to the fine texture of its foliage and the gentle sway of its cascading branches.

ToxicityTo humans
The plant commonly known as Lawson's cypress is not highly toxic to humans. While it is not typically considered edible and ingestion should be avoided, it does not possess severe toxins that are known to cause serious harm if accidentally consumed in small amounts. However, there may be individuals with specific allergies or sensitivities who could experience mild stomach upset or dermatitis upon contact or ingestion. It is advisable to handle plants with care and keep them out of reach of children, who might be more tempted to ingest plant material.
To pets
Lawson's cypress is not known to be particularly toxic to pets such as cats and dogs. If pets happen to ingest a small amount of the plant, it is unlikely to cause significant harm. However, large amounts of ingestion could potentially lead to gastrointestinal upset, as with many non-food plants. To maintain pets' health and safety, preventing them from consuming plants is generally a good practice. If you suspect your pet has ingested a substantial amount of Lawson's cypress or is showing signs of illness, it is best to consult a veterinarian.

WaterThe Weeping Alaskan Cedar requires regular watering to maintain moist, well-drained soil, especially during dry spells. Water the tree with about 1 to 2 gallons of water per week, adjusting as needed for rainfall and weather conditions. During the first growing season, it's important to water deeply once or twice a week to help establish a strong root system. For mature trees, deep, less frequent watering is preferred to encourage deep root growth. It's best to water in the mornings or evenings to reduce evaporation and ensure the water penetrates the soil.
LightWeeping Alaskan Cedar thrives best in full sun to partial shade. It requires an area that receives at least 6 hours of direct sunlight daily, though it can tolerate some light shade. Avoid placing it in deep shade, as this can lead to sparse foliage and a less vigorous plant. An ideal spot would be one where it's exposed to the morning sun and protected from the intense afternoon heat.
TemperatureThe Weeping Alaskan Cedar is hardy and can tolerate a temperature range from about -20 degrees Fahrenheit to 70 degrees Fahrenheit. However, it grows best in temperatures between 40 and 60 degrees Fahrenheit. Avoid exposing the tree to prolonged temperatures above 80 degrees Fahrenheit, as it can stress the plant.
PruningPrune the Weeping Alaskan Cedar to maintain its shape and remove any damaged or diseased branches. The best time for pruning is late winter or early spring before new growth starts. Pruning annually or as necessary can help manage the size of the tree and encourage a more dense, attractive form. Avoid heavy pruning, as this can damage the tree.
CleaningAs needed
SoilLawson’s Cypress 'Imbricata Pendula' thrives in moist, well-drained acidic soil with a pH of 5.0 to 6.0. A soil mix with peat moss, compost, and perlite or sand is ideal to ensure good drainage and aeration.
RepottingLawson’s Cypress 'Imbricata Pendula' typically does not need regular repotting as it is a slow-growing tree. Repot young plants every 2-3 years; mature plants rarely need repotting and prefer undisturbed roots.
Humidity & MistingLawson’s Cypress 'Imbricata Pendula' does well in moderate to high humidity levels, which mirror its natural habitat in the Pacific Northwest.

Life cycleChamaecyparis lawsoniana 'Imbricata Pendula', commonly known as Lawson's Cypress, begins its life cycle with seed germination, which is influenced by moisture, temperature, and light conditions. The emergent seedlings quickly establish a root system and begin to grow upward with feathery, pendulous foliage that characterizes this cultivar. After a few years, the plant enters the juvenile phase, developing a conical shape with branches that weep gracefully, eventually maturing into a stately tree reaching up to 200 feet in its native habitat. Sexual maturity is reached in several years, when the Lawson's Cypress begins to produce cones—small male cones release pollen, which fertilizes the female cones leading to seed development. The mature phase can last for many decades, where the tree undergoes continuous cycles of growth, reproduction, and cone production. In the final stage of its life cycle, the Lawson's Cypress may succumb to age, environmental stress, or disease, leading the tree to decline and eventually die, returning nutrients to the soil upon decomposition.
PropogationPropogation time
Spring-Early Summer
Propogation: Chamaecyparis lawsoniana 'Imbricata Pendula', commonly known as the Weeping Lawson's Cypress, is typically propagated through semi-hardwood cuttings. The best time for taking cuttings is during the late summer to early fall, when the wood is partially matured. The process involves selecting healthy, disease-free semi-hardwood stems and cutting pieces of about 4 to 6 inches (approximately 10 to 15 cm) in length. Cuttings should have several leaf nodes and be taken just below a node, as this is where the rooting hormone can be most effectively applied. The base of the cutting is then dipped in rooting hormone to encourage root development and is planted in a well-draining rooting medium such as a mixture of peat and perlite. To maintain high humidity around the cutting, a plastic cover or dome can be used. The cuttings are kept in a sheltered location with indirect light until they root, which usually takes several weeks to a few months.
