ABOUT
The plant known commonly as 'Snow White' Lawson Cypress is an attractive evergreen with a distinctive appearance. The foliage is lush and primarily a deep green color, which serves as a backdrop for the creamy white tips of the new growth, giving the plant a speckled 'snow-dusted' look.

The overall effect is a striking variegated pattern that catches the eye, making the 'Snow White' Lawson Cypress a popular choice for adding texture and variegation to the landscape. The needles are small and scale-like, closely hugging the stems, contributing to the plant's fine texture. The branches grow in a somewhat horizontal fashion but with a slight upward sweep, adding to the plant’s elegant structure. The overall visual appeal of the plant lies in its color contrast and soft, fluffy appearance, reminiscent of a winter landscape.

- Water
The Lawson's Cypress 'Snow White' prefers consistent moisture and should be watered once a week with approximately 1-2 gallons of water, depending on the size of the plant and the weather conditions. During hotter periods, the plant may require additional water to prevent the soil from drying out. It's important to water deeply and directly at the base of the plant to ensure that the water reaches the root system. During the winter, you can reduce watering since the plant's water requirements decrease. Always check the top few inches of soil for dryness before watering to avoid overwatering.
- Light
Lawson's Cypress 'Snow White' thrives in a location with full sun to partial shade. It does best with at least 4-6 hours of direct sunlight daily, but can tolerate some light shade, especially in hotter climates. Avoid placing it in deep shade as this can lead to poor growth and reduced foliage density.
- Temperature
Lawson's Cypress 'Snow White' can tolerate a range of temperatures but performs best when the climate is between 40°F and 70°F. It can survive colder temperatures down to around -30°F and withstand heat up to about 90°F, but prolonged exposure to extremes can stress the plant.
- Pruning
Prune Lawson's Cypress 'Snow White' minimally to maintain its natural shape and to remove any damaged or dead branches. The best time to prune is in the late winter or early spring before new growth starts. It does not require regular shaping; however, light pruning can be done annually to encourage denser foliage.
- Cleaning
As needed
- Soil
The Snow White Lawson Cypress prefers well-draining, moist soil with a slightly acidic to neutral pH between 5.5 and 7. A mixture of peat, sand, and loamy soil would be ideal to provide proper aeration and moisture retention.
- Repotting
Snow White Lawson Cypress generally does not require frequent repotting and can be repotted every 2-3 years or when rootbound. It's best to repot in spring or early summer.
- Humidity & Misting
Snow White Lawson Cypress thrives in moderate humidity levels. Aim for 40-60% relative humidity to maintain good health without the need for frequent adjustments.

- Life cycle
Lawson's Cypress 'Snow White' begins its life cycle as a seed, which germinates in favorable conditions to produce a young seedling. As it grows, the seedling enters a juvenile phase where it forms roots, stems, and foliage, characterized by rapid growth and development. As the plant matures, it enters the adult vegetative stage, during which it develops a stable structure and distinctive variegated foliage – creamy-white tips against green needles. Around this stage, the plant may be cultivated through cuttings to create genetically identical clones. The plant does not typically produce cones until it reaches maturity, which can take several years. Throughout its life, which can span several decades if conditions are favorable, Lawson's Cypress 'Snow White' requires maintenance such as pruning to maintain its desired shape and promote dense, healthy growth.
- Propogation
Propogation time
Spring-Early Summer
The most popular method for propagating the Lawson's Cypress 'Snow White' is through semi-hardwood cuttings. This process typically takes place in late summer. Cuttings should be about 4 to 6 inches (10 to 15 centimeters) long, taken from the current year's growth. The lower end is trimmed just below a node, and the lower foliage is removed to expose the stem. Next, the bottom end is dipped in a rooting hormone to enhance root development. The prepared cutting is then inserted into a moistened mix of half peat and half perlite or sand to provide suitable drainage and aeration. The cuttings must be kept in a warm environment with high humidity and indirect light until rooting occurs, which generally takes several weeks. During this period, it is crucial to maintain consistent moisture but avoid overwatering to prevent rot.
