Arizona cypress 'Pyramidalis'


The Arizona Cypress 'Pyramidalis' is an evergreen conifer known for its strikingly dense and columnar shape. The foliage of this plant is a rich, blue-green color, consisting of small, scale-like leaves that tightly overlap along slender branches, giving it a somewhat textured look. The leaves may also have a glaucous, or slightly grayish, wax coating that adds to the blue tint of the foliage. As the name 'Pyramidalis' suggests, the plant's overall growth habit is pyramid-like, with a broader base tapering smoothly up to a sharp point at the top. The branches of the Arizona Cypress 'Pyramidalis' extend outward from the central trunk forming a compact, conical silhouette. This tightly packed branch structure provides dense coverage, making it an excellent choice for a privacy screen or a windbreak when planted in a row. The bark on the trunk and main branches is fibrous and stringy with a reddish-brown color that provides a pleasing contrast with the blue-green foliage. During the growing season, the Arizona Cypress 'Pyramidalis' may bear small, round cones that start off green and mature to a woody brown color. These cones are generally modest in size and add to the decorative appearance of the tree. With its striking form and attractive foliage, the Arizona Cypress 'Pyramidalis' is a popular choice for landscapes needing vertical accents or formal hedges without taking up a large footprint. Its beauty and versatility make it a sought-after specimen for both residential and commercial planting schemes.

  • water dropWater

    The Arizona Cypress 'Pyramidalis' should be watered deeply and infrequently to encourage a strong, deep root system. A newly planted tree requires watering once or twice a week, applying approximately 10 gallons each time, depending on the size of the tree and the weather conditions. Once established, reduce watering to every two to three weeks, with increased intervals during cooler months. During hot, dry spells, it may need supplemental water. Adjust watering frequency based on rainfall, as the soil should be allowed to dry out between watering.

  • sunLight

    The Arizona Cypress 'Pyramidalis' thrives best in full sun, where it receives at least six hours of direct sunlight daily. The ideal spot for the plant is an open area, away from large buildings or shade-providing trees, as this cypress variety prefers ample sunlight to develop its dense, pyramidal form.

  • thermometerTemperature

    The Arizona Cypress 'Pyramidalis' is tolerant of a wide range of temperatures and can survive minimum winter temperatures of about 0°F. It can endure summer heat up to about 100°F. The ideal temperature conditions for this cypress fall between 40°F and 80°F, making it suitable for many temperate climates.

  • scissorsPruning

    The Arizona Cypress 'Pyramidalis' typically requires little pruning, which is mainly to maintain its shape or remove dead or damaged branches. Pruning is best done in the late winter or early spring before new growth begins. Thin out dense foliage to allow light into the inner parts of the tree and trim back any wayward branches to maintain its pyramidal shape. Pruning every few years should be sufficient, unless used for a hedge where it may need more frequent trimming to keep the desired form.

  • circleLife cycle

    'Arizona Cypress 'Pyramidalis'' starts its life as a seed, produced by the mature cones of parent trees, which typically require a fire or a period of dryness to open and release seeds. Once germinated in suitable conditions, it grows rapidly into a seedling, establishing a root system and a small shoot. As it matures into a sapling and then a young tree, it develops its characteristic pyramidal shape with dense, scale-like leaves and begins to produce its own cones after reaching a certain age, which varies but can be several years. Throughout its adulthood, it continues to grow taller and thicker, potentially reaching up to 60 feet in height, and it maintains its pyramidal form. The tree exhibits seasonal changes with growth slowing down during the cold months and accelerating in the spring and summer. It can live for several decades, and upon reaching the end of its life cycle, the tree will ultimately die, decompose, and contribute nutrients back to the soil, supporting the growth of new plants.

      Spring-Early Summer

    • The Arizona Cypress 'Pyramidalis', commonly referred to as the Arizona Cypress, can be propagated effectively through seed or cuttings. However, the most popular method involves taking semi-hardwood cuttings. This process is typically done in the late summer or early fall when the current year's growth has begun to harden. Cuttings should be about 6 to 8 inches long, including several sets of needles. It is recommended to take cuttings from the middle part of the branches, where the wood is neither too old nor too young. The cut end of the cutting can be treated with a rooting hormone to promote root development and then planted in a well-draining medium such as a mix of peat and perlite kept consistently moist. The cuttings should be kept under a light shade and high humidity until roots have formed, which can take several weeks to a few months.
